Question

The base of an isosceles triangle is 7cm and its perimeter is 16cm. Length of each of equal sides is​

Answer 1

Step-by-step explanation:

As in isosceles triangle two sides are equal.

So let the equal side be x

Perimeter = 16cm

7cm+x cm+ x cm =16cm

7cm + 2x cm = 16cm

2x= 16cm -7cm

2x= 9 cm

x = 4.5cm

therefore length of each equal side is 4.5cm
