Answer 2

Answer:

The length of equal sides is 16cm.

Step-by-step explanation:

Given:

Perimeter of an isosceles triangle(P)=80cm

length of base(b)=48cm

Length of equal sides=? let it be a.

To find the length of equal sides

Solution:

We have

$P=2a+b$

80=2×a+48

80 - 48=2a

a=16cm

Thus, the length of equal sides is 16cm.
