We are given:

A rectangular glass pane with

W = 91.1 cm
L = 155.9 cm

We are asked to determine the area of the rectangle. The formula of the area of the rectangle is

A = l x w
A = 91.1 cm x 155.9 cm
A = 14202.49 cm^2

Answer:

option (a)

Explanation:

width, w = 91.1 cm, length, l = 155.9 cm

Area = length x width

Area = 155.9 x 91.1 = 14202.49 cm^2

There should be three significant figures in the result.

Area = 14200 cm^2
