Find the area of the kite QRST. HELP PLEASE!!!

Svetradugi [14.3K]

ANSWER

D. 135 m^2

EXPLANATION

The area of a kite is half the product of the diagonals.

The first diagonal is

9m+6m=15m

Note that the vertical diagonal is the axis of symmetry of the kite.

This diagonal bisect the kite

Therefore the second diagonal is

2(9m)=18m

The area of the kite

$= \frac{1}{2} \times 18 \times 15$

$= 9 \times 15$

$= 135 {m}^{2}$

Notice that 8 can be written in exponential form of $2^{3}$

When you see $(2^{3} )^{\frac{8}{3} }$ , recognize that $(a^{m} )^{n} =a^{mn}$

3 × $\frac{8}3}$ = 8

Hence, the answer is $2^{8}$ . Which means 256.

Here is some indices rules/formulas you might find helpful as well:

$a^{m} * a^{n} =a^{m+n} \\\\ a^{m} /a^{n} =a^{m-n} \\\\ (a^{m} )^{n} =a^{mn} \\\\ a^{-m} =\frac{1}{a^{m} }$
