vodomira [7]

The area of the shape shown in the image which is in the shape of kite figure is 168 squared centimeters.

<h3>What is the area of the kite figure?</h3>

The area of the kite figure is half of the product of its diagonals. Area of kite figure can be find out using the following formula.

A=\dfrac{pq}{2}

Here, p and q are the diagonals of the kite.

The length of the first diagonal of the kite figure is,

p=6+15

p=21 cm

The length of the second diagonal of the kite figure is,

q=8+8

q=16 cm

Thus, the area of kite figure is:

A=\dfrac{21\times16}{2}\\A=\dfrac{21\times16}{2}\\A=168\rm\; cm^2

Thus, the area of the shape shown in the image which is in the shape of kite figure is 168 squared centimeters.

Can someone please help me with this multiple choice question?
iVinArrow [24]
1) the small and large triangles are similar, then we can write:

x/24 = 8/18
Cross multiplication → 18x = 24.8 → 18x = 192 and x = 192/18

and x = 32/3 Or 10 ²/³

2) Δ ABC is similar to Δ EDC Since:

∠A = ∠D = 90°

∠C is common
