Question

(05.02)An artist is designing a kite like the one show below. Calculate the area to determine how much material she will need to create the kite.

A kite with two top triangles with height of 7 inches and a base 9.5 inches. The bottom two triangles share the base but have a height labeled 12 inches.

38 square inches
66.5 square inches
114 square inches
180.5 square inches

Answer 1

help plzzzzzz

Answer 2

One diagonal is 7+12 = 19 inches
The other diagonal is 9.5+9.5 = 19 inches
In this case, both diagonals are the same length (though other times this won't be the case)

To find the area of a kite, you multiply the length of the diagonals and then divide by 2
\(\large \text{Area} = \frac{a*b}{2}\)
a,b are the two diagonal lengths. So you'll plug in a = 19 and b = 19.

Answer 3

so it is 19?

Answer 4

\(\large \text{area} = \frac{a*b}{2} = \frac{19*19}{2} = ??\)

Answer 5

The answer isn't 19

Answer 6

sooooooo what is it plz tell me

Answer 7

what is 19 times 19 equal to?

Answer 8

361

Answer 9

right?

Answer 10

Yes, now we cut that in half
361/2 is equal to what?

Answer 11

180.5

Answer 12

Correct. That's the final answer

Answer 13

ok yay thanks

Answer 14

No problem
