Question

The combined perimeter of the rectangle and triangle is 63 inches. The model shows the dimensions of the rectangle. What is the perimeter in inches of the triangle?

Answer 1

*See diagram in the attachment

Answer:

27 inches

Explanation:

Combined perimeter = perimeter of rectangle + perimeter of triangle = 63 inches

Perimeter of rectangle = 2(L + W)

L = 11 in.

W = 7 in.

Perimeter of rectangle = 2(11 + 7) = 36 in.

Let perimeter of the triangle be represented by x

Therefore:

36 + x = 63

Subtract 36 from each side

x = 63 - 36

x = 27

Perimeter of triangle = 27 inches
