Marco's class is painting a mural on the side of their school. The mural covers a 3 m high,

rectangular wall. It has an area of 28 m².
What is the length of the mural?

Answer 1

28/3 = 9 1/3 ≈ 9.33 meters

Explanation:

You want the length of a 28 square meter mural that is a rectangle 3 meters high.

Area

The area of a rectangle is given by ...

A = LW

Solving for L, we have ...

L = A/W = (28 m²)/(3 m) = 28/3 m

The length of the mural is 28/3 meters, or 9 1/3 meters, about 9.33 meters.
