Question

The diagonales of this rhombus are 20 millimeters and 7 millimeters.

Answer 1

The rule of the area of the rhombus using its 2 diagonals is

`A=(d1* d2)/(2)`

Since the diagonals of the given rhombus are 20 mm and 7 mm

Then d1 = 20 and d2 = 7

Substitute them in the rule above

`\begin{gathered} A=(20*7)/(2) \\ A=(140)/(2) \\ A=70mm^2 \end{gathered}`

The area of the rhombus is 70 square millimeters
