Step-by-step explanation:
X+5=2x-7
x=12
y=12+5
y=17
(12, 17)
Given:
The length of diagonals of a rhombus are 12 ft and 5 ft.
To find:
The area of the rhombus
Solution:
Area of a rhombus is:
![Area=\dfrac{d_1d_2}{2}](https://tex.z-dn.net/?f=Area%3D%5Cdfrac%7Bd_1d_2%7D%7B2%7D)
Where,
are two diagonals of the rhombus.
It is given that the length of diagonals of the rhombus are 12 ft and 5 ft.
Putting
, we get
![Area=\dfrac{12\times 5}{2}](https://tex.z-dn.net/?f=Area%3D%5Cdfrac%7B12%5Ctimes%205%7D%7B2%7D)
![Area=\dfrac{60}{2}](https://tex.z-dn.net/?f=Area%3D%5Cdfrac%7B60%7D%7B2%7D)
![Area=30](https://tex.z-dn.net/?f=Area%3D30)
Therefore, the area of the rhombus is 30 square ft.
