Question

The width of a rectangle is 12 cm less than the length the perimeter is 156 cm. Which equations represents how to find the length and the width?​

Answer 1

x+x+x+12+x+12=156

width is 33

length is 45

Explanation:

for for the width we will substitute it for x, and for the length we will substitute for x + 12 since the width is 12 cm less than the length. and, we know that to find the perimeter, you just have to add the widths and lengths. and since the perimeter is given the equation is:

x+x+x+12+x+12=156

width is 33

length is 45
