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
