Evan cut a triangular piece of cloth to use in a quilt. The perimeter of the cloth is 9¾cm. The base of the triangular cloth is 2 ¼cm. The remaining two sides are the same length. Choose the expression to find the length of the other two sides of Evan’s cloth.

9¾ − 2s = 2 ¼
, , 9¾ , − , 2s , = , 2 ¼

2 ¼ −2s = 9¾
, , 2 ¼ , −, 2s , = , 9¾,

9¾ + 2s = 2 ¼
9¾ +, , 2s , = , 2 ¼, ,

9¾ − s = 2 ¼
9¾ , − , s , = , 2 ¼
