Question

Evan cut a triangular piece of cloth to use in a quilt. The perimeter of the cloth is 934 cm. The base of the triangular cloth is 214cm. The remaining two sides are the same length.

Choose Yes or No to tell if each expression models how to find the length of the other two sides of Evan’s cloth.

Please help me

Answer 1

One expression for the length of one of the equal sides

is x = (934 - 214) / 2.

Explanation:

The perimeter is the sum of the 3 sides of the triangle.

2x + 214 = 934

2x = 934 - 214 = 720

x = 720 /2 = 360 cm.
