Find the area of a rectangle in which one side is 3 times larger than the other, and the length of the longer side is 6 cm.

Any rectangle has a length and a width. The biggest of its sides is length.
And according to the condition of the problem, they make it clear to us that its largest side, that is, the length is 6 centimeters.
Let’s find the width of our rectangle.
It is 3 times less than its length. Divide our length by three.
6/3 = 2 – centimeters width of the rectangle.
We know the formula by which the area is determined:
S = a * b.
Let’s plug in our numbers.
S = 2 * 6 = 12 – cm2 area of a rectangle.
Answer: the area of our rectangle is 12 cm2.
