Answer:

390

Explanation:

First find the missing side of the top rectangle.

30 - 20 = 10

Now that you know 10 is the missing length, you can find the area for the top rectangle.

10 x 25 = 250

For the bottom rectangle do the same thing to find the area. (Length times Width) (L x W)

7 x 20 = 140

Now, add up both of the areas to find the complete area of the composite shape.

250 + 140 =390

Answer:

390 ft^2

Explanation:

Lets make the shape into two rectangles

1st: 7 ft by 30 ft

Area = 7*30 = 210 ft^2

2nd: 25ft -7 ft = 18 ft by 30ft -20ft = 10 ft

Area = 18 *10 = 180 ft

The total area is the sum of the two rectangles

210 + 180 = 390 ft^2
