Given that, the length and breadth of the tiles are 12 cm and 5 cm Therefore, the area of the tiles  = length  breadth = 12 cm  5 cm = 60 cm2 Now, (a) For 100 cm and 144 cm rectangular region, Area of region =  length  breadth                         = 14,400 cm2 Therefore, the number of tiles needed =  tiles (b)  For 70 cm and 36 cm rectangular region, Area of region = ...
(a) Split the given figure into a small rectangle, as shown here; Now, the area of the rectangle (I) =  = 12  2 =   the area of the rectangle (II) =  = 8  2=   Therefore, Total area = (b) Split the given figure into a small rectangle, as shown here; Now, the area of the rectangle (I) =  = 7 7 = the area of the rectangle (II) =  = 21  7= Now, the area of the rectangle (III) =  = 7 7 =...
(a) Split the given figures into small rectangular parts as shown here; Now, the area of the rectangle (I) =  = 4  3 = 12  the area of the rectangle (II) =  = 3  2= 6  the area of the rectangle (III) =  = 4  1 = 4  the area of the rectangle (IV) =  = 3  2 = 6  So, the total area of the figure = sum area of all rectangles                                                  = (12 + 6 + 4 +...
Given that, Length and breadth of the land are 5m and 4 m. Side of the square flower bed = 1m Therefore the area of the bed = 1  So, Area of 5 square flower bed = 5  Area of the and = length  breadth                          =  Thus, the area of the remaining part of the land = Area of land - area of the flower bed                                                                          ...
Given that, Length of the floor = 5 m and its width = 4 m Therefore,  the area of the floor = length  breadth And, side of the square carpet = 3m Therefore,  the area of the square carpet =  = 3m  3m = 9m2 Thus, the area of the floor which is not covered with carpet =
Given that, Length of the room = 4 m And it's breadth = 3.5 m Area of the room = = length  breadth                                                              =  Hence the area of carpet needed is
Given that, Length of the table-top = 2m and it's breadth = 1.5 m Therefore, the area of the tabletop  = length  breadth
Given that, Length of the rectangular plot = 500m  and the width = 200 m fencing cost  = Rs 8 per hundred sq. meter Therefore, the area of the plot   =  Now, Total rate of tiling of 100,1000 m2   =                                                                   = Rs 8000
Given that, Area of the rectangular garden = 300 sq. m and the length = 50 m Therefore, the Width of the garden =                                                           = Hence the width of the garden is 6 m
We know that area of a rectangle = length  breadth Therefore, (a) Here length is 9m and the breadth of the rectangle is 6m        So, the area of the rectangle        =  (b) Here length is 17 m and the breadth of the rectangle is 3m        So, the area of the rectangle         =  (c) Here length is 4m and the breadth of the rectangle is 14m        So, the area of the rectangle       ...
It is known that area of a square =  (a) The length of a side of a square = 10cm So, the area =  (b)The length of a side of a square = 14cm So, the area = (c) The length of a side of a square = 5m So, the area =
We know that area of a rectangle = length  breadth Therefore, (a) Here length is 3cm and the breadth of the rectangle is 4cm        So, the area of the rectangle          =  (b) Here length is 12m and the breadth of the rectangle is 21m        So, the area of the rectangle          =  (c) Here length is 3km and the breadth of the rectangle is 3km        So, the area of the...
