Question

The perimeter of an equilateral triangle is 63 inches. Suppose a square is constructed with each side being 2 inches shorter than each side of the triangle, and then 3 inches are added to each side of the triangle. How many inches would the total combined perimeters of the triangle and square be?

Answer 1

Combined perimeters of the triangle and square will be 148 inches

Step-by-step explanation:

An equilateral triangle has all its sides have equal length. The perimeter is 3l where l is length of one side.Given the perimeter of the equilateral triangle as 63 inches then,finding the length of each side will be:

3l=63

l=63/3=21 inches.

Square has its lengths 2 inches shorter than each side of triangle,this will be;

21-2=19 inches

Perimeter of the square will be 4l = 4*19=76 inches

In the new triangle 3 inches are added to each side,thus the new side will be;

21+3=24 inches.

New perimeter of triangle will be: 3l = 3*24=72 inches

The new combined perimeter will be 76+72=148 inches.
