Question

A rug is shaped like a rectangle whose perimeter is 176 ft. The length is 7 times as long as the width. Find the length and the width.

Answer 1

P = 2l + 2w; unde P = the perimeter of rug; l = the length; w = the width;
176 = 2l + 2w;
Then, l = 7w ;
_______________
176 = 2*7w + 2w;

176 = 14w + 2w;

176 = 16w;

w = 176÷16;

w = 11ft;

l = 7 * 11;

l = 77ft;
