Question

A wall in Marcus's bedroom is 8 2/5 feet high and 16 2/3 feet long. If he paints 1/2 the wall blue, how many square feet will be blue?

Answer 1

70 ft^2

Explanation:

Find the area of the wall

A = l*w where l is the length and w is the width

A = 8 2/5 * 16 2/3

Change to improper fractions

A = 42/5 *50/3

Rewriting

A = 42/3 * 50/5

= 14 * 10

A = 140 ft^2

He paints 1/2

1/2 (140) = 70 ft^2
