What is the area of a rectangular area if its length is 40 m and its width is 2 times less?

To find the area of a rectangle, you need to multiply its length by its width. Since, according to the condition of the problem, we are given the length, but not the width, we must find it. It is said that the width is half the length of the rectangle, so we have to divide the length by 2.

1) 40/2 = 20 (m) – width

Now we can search for the area using a mathematical formula, where the area of the rectangle is S = a * b.

2) 40 * 20 = 800 (m2)

Answer: the area of a rectangular area is 800 m2.
