Problema Solution

The two equal legs of an isosceles triangle are each 8 cm longer than the base of the triangle. Let b represent the a base. write an expression for the perimeter of the triangle

Answer provided by our tutors

If the legs are of equal length and each is 8 cm longer than the base,

that means the length of the three sides is b, b+8, and b+8.


The perimeter is the sum of all the side lengths.


Add the lengths of the sides together, getting b + b+8 + b+8.

That can be written as b+b+b + 8+8, and this gives 3b + 16.
