225.00 square meters
527.34 square meters
337.50 square meters

Answer 1

Answer:

E. The area of the rectangle is 337.5 square metres

Step-by-step explanation:

Given

Shape: Rectangle

Perimeter = 75 m

Length = 1.5 * Width

Required:

Area of the rectangle

First, the value of the length and the width of the rectangle need to be calculated.

Let L and W represent the length and width of the rectangle, respectively.

Hence,

Length = 1.5 * Width can be represented by

L = 1.5 * W

L = 1.5W

Also, let P and A represent the perimeter and area of the rectangle.

Using the formula of perimeter; we have

P = 2(L + W)

By substituting 1.5W for L and 75 for P, the equation becomes

75 = 2(1.5W + W)

75 = 2(2.5W)

Open bracket

75 = 5W

Divide through by 5

15 = W.

Recall that L = 1.5W

So, L = 1.5 * 15

L = 22.5

Since L and W represent the length width of the rectangle,

Then

Length = 22.5m and Width = 15m

Area of a rectangle is calculated by multiplying its length by its width.

So,

Area = 22.5m * 15m

Area = 337.5 m²

Hence, the area of the rectangle is 337.5 square metres
