Answer:
189.3 in.²
Step-by-step explanation:
The shape consists of a half circle and a rectangle. Therefore,
Area of the shape = area of the half-circle + area of the rectangle
= ½(πr²) + L*W
r = radius of the half-circle = ½(10) = 5 in.
L = length of the rectangle = 15 in.
W = width of the rectangle = 10 in.
Plug in the values
Area of the shape = ½(π*5²) + 15*10
Area of the shape = 39.27 + 150
= 189.27 ≈ 189.3 in.² (Nearest tenth)

The value of 7 in 26,475 is ten times greater than the value of 7 in 503,497.
This is because the first 7 is in the tens place and the second seven is in the ones place. Everytime you move to the next "place" you are basically making the number ten times smaller or greater.
Area of square = x^2
If length is multiplied by 3, then each side of square is now 3x
new Area = (3x)^2 = (3x)*(3x) = 9x^2
So the Area has increased by a factor of 9.
In general, the Area will always increase by a factor which is the square of the factor applied to the side length.
