Question

The length of a rectangle is six times its width. The area of the rectangle is 384 square centimeters. Find the dimensions of the rectangle.

Answer 1

the width is 8
the length is 48

Answer 2

Width = 8 cm

Length = 48 cm

Explanation:

Area of a Rectangle Formula: A = lw

Step 1: Write out expression:

l = 6w

w = w

Step 2: Plug in known variables

384 = 6w(w)

Step 3: Solve for w

385 = 6w²

w² = 64

w = 8

Step 4: Find l

l = 6(8)

l = 48
