Question

A wire was bent into the shape of a rectangle with width 5 and length 7. If the same wire is bent into the shape of a square, what is the length of a side of the square? 3 B

Answer 1

Perimeter = 2(L+B) = 2(7+5) =2(12) = 24

Perimeter of a square = 4L

24 = 4L

Dividing through by 4, we get,

L =24/4

L = 6 units. (option B)
