Question

C The area of the kite is 28 m². What is the value of x? -X m 10 m 4 m -x m X= (Type an integer or a decimal.)

Answer 1

We have the next formula for the area of a kite

$A=\frac{d1\cdot d2}{2}$

where

A=28m^2

d1=10+4=14

d2=2x

we substitute the values into the formula of the area

$28=\frac{(14)\cdot(2x)}{2}$

In order to find the value of x we need to isolate the x

$\begin{gathered} 28=7x \\ 7x=28 \\ x=\frac{28}{7} \\ x=4 \end{gathered}$

the value of x=4
