A rectangular hallway has an area of 70 ft squared. The width of the hallway is 4 feet. What is the length of the hallway

The length of the rectangle is 17.5ft

Step-by-step explanation:

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

a = area = 70ft²

l = length

w = width = 4ft

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 = 70ft² / 4ft

l = 17.5ft

The length of the rectangle is 17.5ft

17.5 is the correct answer
