your art class is designing a 294 square foot mural that is to be six times as long as it is wide.How long should it be? How wide?

Question

not sure how to sovle it

Answer 1

The area of the mural, A = 294 ft²

 

Area of rectangle equals length times width. Given that the length equals six times the width.

 

L = 6W

L/6 = W

 

replace W in

A = L*W

 

294 = L*L/6 

 

294*6 = L²

 

1764 = L²

 

Sqrt(1764) = L

 

42 = L
