Question

A rectangular pan has a length that is 4/3 the width. The total area of the pan is 432 in^2. What is the width of the pan?

Answer 1

Answer: 18

Explanation:

A = l x w

324 = 18 x 18

432 = 324 x 4/3

432 = 4/3 x 18^2

Answer 2

From the formula for finding the area of a rectangle,
A = l*w
432 = 4/3*w
cross multiply to get
3*432 = 4w
1296 = 4w
divide both sides by 4 to get
w = 324in square
