Answer:
x+x+x+12+x+12=156
width is 33
length is 45
Step-by-step 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
