Question

A rectangular board is 1.8 meters long and 1.5 meters wide. What is the area of the board in square millimeters?

Answer 1

It is quite easy to find area. You should simply multiply the 2 distances.

A=lw
A=1.8*1.5
A=2.7

Then, we must convert to millimeters. You can do this by multiplying 2.7 by 1000.

The area of the rectangular board is 2,700 mm squared.
