Calculate the perimeter of the rectangle, the side is 6 m. And the area of the wound is 72 m2

Calculate the perimeter of the rectangle, the side is 6 m. And the area of the wound is 72 m2 and the area is calculated if the side is 15 m. And the perimeter is 90 m.

Objective 1.

First, we find the length of the unknown side of the rectangle.

We divide the area by 6 meters.

72/6 = 12 m.

To find out the perimeter of a shape, you need to add all the sides of the rectangle.

12 + 6 + 12 + 6 = 24 + 12 = 36 meters.

Objective 2.

Determine the sum of the length and width of the rectangle.

We divide the specified perimeter into 2 equal parts.

90/2 = 45 m.

Find the length of the unknown side.

To do this, subtract 15 meters from the found sum of the sides.

45 – 15 = 30 m.

So the area of the figure will be equal to:

30 * 15 = 450 m2

Answer:

36 m, 450 m2
