Question

The perimeter of an isosceles triangle is 23 cm. The base is 4 cm less than one of the equal sides. Find the length of each side.

Answer 1

Since it is an isos. triangle we know that both sides are equal
Let's let the base=b and the legs =L
We know that B=L-4
And L-4+L+L=23
3L-4=23
3L=27
L=9
