The glass window pane has an area of 80 square centimeters. The width of the pane is 8 centimeters.

The length is 10 cm

Step-by-step explanation:

The area is given by length times width

A = l*w

We have an area of 80 cm^2 and a width of 8

80 = l*8

Divide each side by 8

80/8 = 8l/8

10 = l

The length is 10 cm

10 cm

Step-by-step explanation:

Area = length * width

80 = length * 8

length = 10
