Question

The diagonales of this rhombus are 7 centimeters and 2 centimeters.

Answer 1

The rule of the area of the rhombus using its diagonals is

$A=\frac{d1\times d2}{2}$

The length of d1 = 7 cm

The length of d2 = 2 cm

Substitute them in the rule above

$\begin{gathered} A=\frac{7\times2}{2} \\ A=\frac{14}{2} \\ A=7\operatorname{cm} \end{gathered}$

The area of the rhombus is 7 square centimeters
