# Find the perimeter of a rectangle if its length is 24 m and width is 45% less.

A rectangle has opposite sides parallel and equal.

The perimeter is calculated by adding the lengths of all sides of the rectangle.

Let’s write down the formula for determining the perimeter of a rectangle:

P = a + b + a + b = 2a + 2b;

P is the perimeter of the figure;

a and b are the length and width of the rectangle.

Let’s compose the proportion and find the width of the rectangle:

24 m – make up 100% of the length;

in m – is 45% of the length;

h = 24 m * 45% / 100% = 10.8 m.

Find the perimeter of the rectangle:

P = 2 * 24 m + 2 * 10.8 m = 48 m + 21.6 m = 69.6 m.

Answer: the perimeter is 69.6 m.
