Question

Carla has a rectangular garden in her backyard. The width of the garden is 9 meters. The area of the garden is 360 square meters. What is the length of the garden? Show your work.​

Answer 1

l = 40 m

Explanation:

The formula for area of a rectangle is

A = lw, where

• A is the area in square units,
• l is the length,
• and w is the width

Step 1: Since we're given the area and width, we plug in these two values for A and w and to solve for l (length):

360 = 9l

Step 2: Divide both sides by 9 to solve for l

(360 = 9l) / 9

40 m = l

Optional Step 3: We can check our answers by checking that the product of 40 and 9 is 360

40 * 9 = 360

360 = 360
