Answer:
44 sq. ft
Step-by-step explanation:
5(2^2) = 20
4(3x2) = 24
20+24 = 44
8y-4x=2x+12y
x+2y+8y-4x=180
10y-3x=180
x+2y+2x+12y=180
14y+3x=180
24y=360
y=15
8(15)-4x=2x+12(15)
120-4x=2x+180
120=6x+180
-60=6x
x=-10
Answer:
104.73cm²
Step-by-step explanation:
AREA OF SEMI CIRCLE
9cm-4cm = 5cm
5cm is the radius of the semi-circle
(πr²)/2 =
25π/2 = 12.5π
AREA OF SQUARE
16cm*9cm = 144cm²
AREA OF THE FIGURE SHOWN
144cm² - 12.5cmπ²
144cm² - 39.27cm² = 104.73cm²
