Question

Math 15

A farm is to be built in the shape of Quadrilateral ABCD, as shown below. All four sides are equal.

A rhombus ABCD is shown with diagonal AC equal to 18. 3 feet and diagonal BD equal to 13.8 feet

What is the area of the farm?

a
73.2 square feet
b
111.2 square feet
c
126.27 square feet
d
168.36 square feet

Answer 1

• c. 126.27 square feet

Explanation:

Area of rhombus is:

• A = pq/2, where p and q are diagonals

We have:

• p = 18.3 ft
• q = 13.8 ft

The area is:

• A = 18.3*13.8/2 = 126.27 ft²

Correct choice is C
