What is the area of a rectangle in cm2 and m2 if it is 4m long by 35 cm high?

Answer 1

First of all, 1 meter is equal to 100 centimeters, and 1 centimeter is equal to 0.01 meters.

To find the answer in centimeters, you need to convert the length of the rectangle from meters to centimeters by multiplying:

4m/1 x 100cm/1m = 400cm

Now you simply multiply using the equation, area = length x width (a = l x w), and substituting in the dimensions, which are 400cm = l, and 35cm = w. Your equation should look like this:

a = 400cm x 35cm

Now you need to multiply on the right side of the equation:

a = 14000cm2

The area is equal to 14000 square centimeters.

To find the answer in meters, you can multiply:

14000cm2/1 x 1m/100cm x 1m/100cm = 14000m2/10000

And reduce:

1.4 square meters or 1 2/5 square meters
