PLEASE HELP!!! Area of trapezoids and triangles ​

PLEASE HELP Area Of Trapezoids And Triangles class=

Sagot :

i want to believe 30...?

Answer: 54 square inches and 18 square inches

Explanation:

The formula for the area of a trapezoid is the sum of the top and bottom bases divided by 2, multiplied by the height.

In the first picture the bases are 6 and 12, and the height is 6, so the formula would look like this:

[tex]\frac{6+12}{2} *6[/tex]

=[tex]\frac{18}{2} *6[/tex]

=[tex]9*6[/tex]

=54

54 [tex]in.^{2}[/tex] is the answer to the first problem.

Following the same method, we can do the next problem the same way:

[tex]\frac{4+8}{2} *3[/tex]

=[tex]\frac{12}{2} *3[/tex]

=[tex]6*3[/tex]

=18

18 [tex]in.^{2}[/tex] is the answer to the second problem.
