Find the area of each part of the trapezoid.

Nikitich [7]

Answer:

Area of Triangle A = 4 cm²

Area of Rectangle = 24 cm²

Area of Triangle B = 4 cm²

Area of Trapezoid = 32 cm²

Step-by-step explanation:

The formula to find the area of a triangle is: $\frac{h_bb}{2}$

The base (b) is 2 and the height (h) is 4.

Now multiply,

2 times 4 = 8

Then divide,

$\frac{8}{2}$ which equals 4.

So the area of Triangle A and B is 4 cm² because they are the same triangles.

The formula to find the area of a rectangle is: a times b.

a=6 and b=4

Multiply,

6 times 4 = 24

So the area of the rectangle is 24 cm²

The formula to find the area of a trapezoid is: $\frac{a+b}{2}h$

A=6

B=10

H=4

So now,

$\frac{6+10}{2}4$

6+10=16

16 divided by 2 is 8.

Last multiply,

8 times 4 is 32.

The area of the trapezoid is 32 cm²

Hope this helped! And have a great day!
