Answer:
Choice A is correct answer.
Explanation:
We have to find the area of a kite where diagonals are given.
From given diagram,we observe that
Let the diagonals are d₁ and d₂.
d₁ = 18 unit and d₂ = 10 units
The formula for area of a kite
A = 1/2 d₁d₂ where d₁ and d₂ are diagonals of kite.
putting given values of diagonals ,we get
A = 1/2(18)(10)
A = 90 sq. units which is the answer.
