Question

Can someone help me with this question please

Answer 1

The formula of an area of a rhombus:

`A=(diagonal_1\cdot diagonal_2)/(2)`

The diagonals bisect each other. That is, they divide each other into two equal parts.

Therefore we have:

`diagonal_1=2\cdot1.2m=2.4m\\\\diagonal_2=2\cdot0.9m=1.8m`

Substitute:

`A=(2.4\cdot1.8)/(2)=2.16\ m^2`

Answer: 2.16 m²
