Question

A window is in the shape of a rectangle with a base of 4 ft and a height of 5 ft. The window has a colored glass in the shape of a kite. Use the grid to identify the area of the colored glass.

Answer 1

10 ft²

Explanation:

A = 1/2 (d1) (d2)

A = 1/2 (4) (5)

1/2 x 20

=10 ft²

Answer 2

A = 10 ft²

Explanation:

Look at the picture.

A₁ = 2 · 2 = 4

A₂ = 2 · 3 = 6

The area of a rhombus:

A = A₁ + A₂ ⇒ A = 4 + 6 = 10

You can use the formula of an area of a rhombus:

`A=(d_1d_2)/(2)`

d₁ = 4, d₂ = 5

Substitute:

`A=((4)(5))/(2)=(2)(5)=10`
