I’m really confused on how to solve this can someone please help me fast!!!!
beks73 [17]

Answer:

130.24

Step-by-step explanation:

8*10+3.14*4^2=

80+50.24=130.24 ft^2

Cut the shape into a semi-circle and rectangle (with length 10 and width 8).

You'll find the radius of the semi-circle is 4.

The area of the rectangle is 80.

Then use the pir^2 formula but replace pi with 3.14

3.14 multiplied by radius 4 squared is 50.24

50.24 plus 80 is 130.24 ft squared.

HELP ME PLS THIS NEEDS TO BE DONE TONIGHT AND TURNED IN TOMORROW The Hamiltons are paving their driveway. They are paving a rect
Rufina [12.5K]

Answer:

1350 ft²

Step-by-step explanation:

First off, I notice that the triangle at the bottom can fit the slant at the top to make a perfect rectangle.

This will leave us with a rectangle. We can add up 4 and 5 for the sum of 9, making one side 9 inches.

5 + 4 = 9 in

We multiply 9 by 3 to get the actual length of that side

9 x 3 = 27 ft.

We multiply 16 and two-thirds by 3 to get the actual length of the other side

16\frac{2}{3} x 3 = 50 ft.

To find the area of this rectangle we multiply length and width

50 x 27 = 1350 ft²
