Answer:

143.79 square feet

Step-by-step explanation:

Find the area of the rhombus first, by using the equation a = 1/2(b1 + b2)h

Basically, find the average base between the two, and multiply that by the height. This gets you 112 feet.

Then, find the area of the half circle, by using the equation a = pi(r^2)

The radius is 4.5, squared is 20.23, times pi is 63.585, divided in half is 31.7925. Add the two areas together in order to get 143.7925

Each side of a rhombus is 20 cm long and one of its diagonals is 24 cm in length, find the area of ​​this rhombus?
vodomira [7]

Answer:

AB = 20 CM

OA = 1

__ × 24 cm

2

= 12 cm

AOB = 90 °

OB² == AB² - OA ²

( {20}^{2} ) - ( {12}^{2} ) \\  = 400 - 144 \\  = 256 \\

ob \:  =  \sqrt{256}  = 16 \\ bd \:  = 2 \times ob \\  = 2 \times 16 \\  = 32cm \:  \\

AREA OF ABCD IS

\frac{1}{2 }  \times ac \times bd \\  =  \frac{1}{2}  \times 24 \times 32 \\ 384cm
