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 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...
