Question

A picture frame is shaped like a rectangle whose perimeter is 196 cm. The length is 6 times long as the width

Answer 1

L=length W=width
perimeter=2Lx2W
196=2L+2W

Length can be written as 6W because it is 6 times the width. We then substitute this in so all the terms are the same

196=2(6W)+2W
196=12W+2W
196=14W
W=14cm
L= (14x6) 84cm
