Question

the diagonals of this rhombus are 8 kilometers and 10 kilometers. what is the area of the rhombus? square kilometers

Explanation:

Step1: Recall area formula

The area formula for a rhombus is $A=\frac{1}{2}d_1d_2$, where $d_1$ and $d_2$ are the lengths of the diagonals.

Step2: Substitute values

Given $d_1 = 8$ km and $d_2=10$ km, we substitute into the formula: $A=\frac{1}{2}\times8\times10$.

Step3: Calculate the area

First, $\frac{1}{2}\times8 = 4$, then $4\times10=40$. So $A = 40$ square - kilometers.

Answer:

40
