Exercise 4 Page 443

We want to find the area of the kite. We can look at the kite as two identical triangles. Remember to find the length of any unknown sides when breaking up the shape.

Now we will find the area of each triangle. We can see that the height h of the triangles is 2 inches and the base b is 14 inches.

We will substitute these values into the formula for the area of a triangle.

A=1/2bh

SubstituteII

b= 14, h= 2

A=1/2( 14)( 2)

Evaluate right-hand side

Multiply

A=1/2(28)

1/b* a = a/b

A=28/2

Calculate quotient

A=14

The area of each triangle is 14 square inches. Finally, we add the area of triangles to find the area of the kite. Area of the Kite 14+14=28in.^2
