Answer:

8 cm

Step-by-step explanation:

A = L x W

40= L x 5

40÷5=L

L= 8cm

Formula for the area of a rectangle: A = length x width

We know the area and the width of the rectangle, so we can use the area equation in order to solve for the length.

40 = l x 5

l = 8

The length of the rectangle is 8 cm.

Hope this helps! :)
