Question

Find the area of the trapezoid shown below and choose the appropriate result.

Answer 1

15 in squared

Area of the square = 4 x 3 = 12
Area of 1 triangle = 3 x 1 = 3/2 = 1.5
Add it all up, square plus 2 triangles =
12 + 1.5 + 1.5 = 15

Answer 2

Answer:

13.5 in²

Step-by-step explanation:

We can use the area formula for a trapezoid.

Area = $\frac{1}{2}(b_{1}+b_{2} )h$

To solve, we find and plug in the variables. According to the trapezoid, we know

h (height) = 3 in

$b_{1}$ (base 1) = 4in

$b_{2}$ (base 2) = 5in

1/2(4 + 5) ·3 = 13.5 in²
