Step by step solution

01

Step 1. Given information.

Given figure is a rhombus.

The two diagonals of rhombus are 4 and 10.

02

Step 2. Concept used.

Area of rhombus can be found using the formula

$A = \frac{1}{2} d_{1} d_{2}$

Where $d_{1} d_{2}$ , are the two diagonals of rhombus.

03

Step 3. Find the Area of given figure.

$A = \frac{1}{2} d_{1} d_{2}$

$= \frac{1}{2} \times 4 \times 10$

$= 2 \times 10$

$= 20$

Therefore, the area of given figure is 20 square units.
