Question

find the area of the rhombus. 9 ft 12 ft 12 ft 9 ft

Explanation:

Step1: Calculate the lengths of the diagonals

The lengths of the diagonals of the rhombus are \(d_1=(9 + 9)\text{ft}=18\text{ft}\) and \(d_2=(12 + 12)\text{ft}=24\text{ft}\).

Step2: Use the formula for the area of a rhombus

The formula for the area of a rhombus is \(A=\frac{1}{2}d_1d_2\). Substitute \(d_1 = 18\) and \(d_2=24\) into the formula:
