Question

the floor of a rectangular desk has an area of 600 square feet. the floor is 20 feet wide. how long is the floor?

Answer 1

A= w*l

Area= 600sq.feet

Wide=20 feet

Long=?

Let’s assume long as ‘x’

So, A=w*l

600=20*l

600/20=l

30=l
Therefore, the floor is 30 feet

Check:

600=20*l
600=20*30
600=600
Therefore, my answer is correct

Answer 2

Length is 30 feet

Explanation:

Area of a rectangle formula: A = LW

Step 1: Make an equation

600 / 20 = 20L / 20

30 = L

Answer: Length is 30 feet
