Question

The diagonal of a rectangular garden measures 111/4m while it's width measures 63/4m . Calculate the perimeter of the garden

​

Answer 1

Explanation:

The diagonal of a rectangular garden forms a hypotenuse with the width and length sides. We can use the Pythogorean Theorem to calculate the remaining side.

Let W, L, and H stand for the Width, Length, and Hypotenuse, all in meters.

W^2 + L^2 = H^2

Enter the data:

(63/4)^2 + L^2 = (111/4)^2

248.06 + L^2 = 770.06

L^2 = 522

L = 22.847 meters

Perimeter is 2W + 2L

Perimeter = 2(63/4) + 2(22.847)

Perimeter = 77.19 meters
