the length of a rectangle is equal to Triple the width. Write a system of equation to determine the dimensions of the rectangle if the perimeter is 88 centimeters. Identify what the variables stand for?

P=2L + 2W

88=2 (3w) + 2w

88=6w + 2w

88=8w

88/8=8w/8

11=w

If the perimeter is 88 and the width is 11 and the length is 3 times the width then the length is 33 and you plug those numbers into the original formula you get the starting perimeter of 88

P=2L + 2W

P=2 (33) + 2 (11)

P=66+22

P=88
