Question

Help me with this! i am confuseddddddd!!

Answer 1

73.5
`cm^(2)`

Explanation:

The shaded area is in the shape of a trapezoid, so to find the area all we have to do is use the formula

`A = (a + b)/(2) h` , where h is height, a is base 1, and b is base 2.

Plugging in the values, work on solving this equation:

`A = ((9) + (12))/(2)(7)`

---------------Math Skip---------------------

We should be left with

`A = (21)/(2)(7) = 10.5 (7) = 73.5 cm^(2)`
