Q.3 The base of an isosceles triangle is cm. The perimeter of the triangle is . What is the length of either of the remaining equal sides?
In isosceles triangles, we have 2 sides of equal length.
Given that its perimeter is cm.
Let's assume the length of the equal side is x cm.
Also,
Transposing to the RHS side it becomes,
Now dividing both sides by 2, we get
Hence, the length of the equal sides of the isosceles triangle is cm.
