Answer:

Answer:  300 ft.²   .

________________________________________________________

Explanation:

________________________________________________________

We need to find the area of the rectangle:

________________________________________________________

Area:  A = L * w = length * width = 12 ft. * 18 ft. = 216 ft.²

________________________________________________________

Then we need to find the area of the TRAPEZOID that is on top of the rectangle:

________________________________________________________

Area:  A = (1/2) * (base 1 + base 2) * height 

 

            = (1/2) * (18 ft. + 10 ft.) * 6 ft.

  

            = (1/2) * ( 28 ft.) * (6ft.)

     

            =   84 ft.²

____________________________________

Now, we add the 2 (TWO) areas together, to get the answer:

  216 ft.²  +  84 ft.²  = 300 ft.²  .

Answer:

300

Step-by-step explanation

You have to divide the figure into two parts

The bottom part is a rectangle so what you'd do is multiply the two values of 12 and 18 together as the formula for area of a rectangle is length x width

18 x 12 = 216

The top part of the figure is a trapezoid, the formula is different for it, but it's also tricky as the base isn't given. However the length of the bottom of the rectangle is the same as the base of the trapezoid. The formula for a trapezoid is ((b1+b2)/2) x h so,

((18 + 10)/2) x 6 = 84

You then have to add the two measurements together to get 300
