Answer:

(A) 142.5 square inches

Step-by-step explanation:

It is given that A kite with two top triangles with height of 5 inches and a base 7.5 inches. The bottom two triangles share the base but have a height labeled 14 inches that is:

DE=5in, EC=7.5in, EB=14in

Now, area of the two top triangles of the kite=[tex]2(\frac{1}{2}{\times}EC{\times}DE)[/tex]

=[tex]EC{\times}DE[/tex]

=[tex]7.5{\times}5[/tex]

=[tex]37.5 square inches[/tex]

Also, area of the two bottom triangles of the given kite=[tex]2(\frac{1}{2}{\times}EC{\times}EB)[/tex]

=[tex]EC{\times}EB[/tex]

=[tex]7.5{\times}14[/tex]

=[tex]105 square inches[/tex]

Therefore, the total area of the kite=area of the two top triangles of the kite+area of the two bottom triangles of the given kite

=37.5+105

=142.5 square inches.
