The area of a rectangle flower bed is 45 square feet. If one side measures 5 feet, what is the length of the other side?

The length of the other side is 9 ft

Step-by-step explanation:

To solve this we first have to know the formula to calculate the area of a rectangle

a = area = 45 ft²

l = length

w = width = 5 ft

a = l * w

because we want to calculate the length, we will have to clear the l

a = l * w

l = a / w

now we replace with the known values

l = 45 ft² / 5 ft

l = 9 ft

The length of the other side is 9 ft

the length of two of the sides will be 5 (the side you already had and the one across from it because they should be the same size) the other two sides will be 9 because Area = Length times Width so if you dived the side you already had by the total then you get the answer for the other two sides

45/5 = 9 so the other two sides are nine
