The height of the rectangle is 75%. Find the perimeter of this rectangle if its area is 48m2.

Let x m be the width of the rectangle.

Let us express the length of the rectangle in terms of x.

75% of x is 0.75x.

Let us express the area of the rectangle in terms of x and solve the equation.

x * 0.75x = 48 m2.

0.75x ^ 2 = 48.

x ^ 2 = 48: 0.75.

x ^ 2 = 64.

x = 8 meters.

Let’s find the length.

0.75 * 8 = 6 meters.

Find the perimeter of the rectangle.

2 * (6 + 8) = 2 * 14 = 28 meters.

Answer: the perimeter of the rectangle is 28 meters.
