Find the area of a rectangle if its length is 5 m and its width is 4 times greater.

We know the length of the rectangle, it is 5 meters, and we also know that the width of the rectangle is 4 times its length.

Let’s find the width of the rectangle for this, increase its length by 4 times.

5 meters * 4 = 20 meters width of the rectangle.

Let’s remember the formula for finding the area.

S = a * b, where a and b are the length and width of the rectangle, respectively.

Substitute and calculate the area of the rectangle:

S = 5 * 20 = 100 square meters of the given rectangle.

Answer: 100 square meters.
