Question

A rectangular solar panel has a length that is 11 inches shorter than 4 times the width. If the perimeter of the panel is 198 inches, what are the dimensions of the panel

Answer 1

Answer:79.2x19.8

Explanation:

Length(L)=4xwidth(w) L=4w

Perimeter(p)=198

P=2L+2w 2L+2w=198

Substitute L=4w in 2L+2w=198

2(4w)+2w=198

8w+2w=198

10w=198

w=198/10

w=19.8

Substitute w=19.8 in L=4w

L=4x19.8

L=79.2
