Question

Nicole's office is 5 m wide and 3 m long. What is the area?

Answer 1

All you use is the area for a rectangle
A=lw
A= 5*3
A=15 sq.m.

Answer 2

Area is calculated as length times width.
In this case, the width is 5 m and the length is 3 m.
5 • 3 = 15
So the area of Nicole's office is 15 square meters.
Square meters because only length and width is 2 dimensional.

Hope this helps!
