A rectangle measures fourteen centimetrers by four centimetres what is its area
The formula for finding the area of a rectangle is:
\(\sf area = length \times width\)
Here we are given that the length is 14 cm, and the width is 4 cm.
So the are will be:
\(\sf area = 14~cm \times 4~cm\\\\\boxed{\sf{area = 56 cm^2}}\)
