Chapter 11.4, Problem 7PSB

To determine

To calculate: The area of kite

Answer to Problem 7PSB

Area of kite is $18$ square units.

Explanation of Solution

Given information :

Diagonals of kite are $4$ and $9$ respectively.

Formula used :

Area of kite = $\frac{1}{2}\times d_1\times d_2$

where $d_1$ and $d_2$ are diagonals of the kite

Calculation: As, diagonals of kite are $4$ and $9$ ,

Area = $\frac{1}{2}\times d_1\times d_2$

  $\begin{array}{l}\Rightarrow \frac{1}{2}\times 4\times 9\\ \Rightarrow \frac{36}{2}\\ \Rightarrow 18\end{array}$
