Answer:
Option (2) is correct.
The area of rhombus is 54 square feet.
Step-by-step explanation:
Given : A rhombus with diagonals 9 ft. and 12 ft.
We have to find the area of a rhombus with diagonals 9 ft. and 12 ft.
Area of rhombus is given by the half the product of its diagonals.
Mathematically written as
[tex]\text{Area of rhombus}=\frac{1}{2}\times d_1 \times d_2[/tex]
Where [tex]d_1\ and\ d_2[/tex] are the diagonals of rhombus.
given : [tex]d_1=9\ and\ d_2=12[/tex]
Subsititue, we have,
[tex]\text{Area of rhombus}=\frac{1}{2}\times 9\times 12[/tex]
Simplify, we have,
[tex]\text{Area of rhombus}=54[/tex]
Thus, the area of rhombus is 54 square feet.
