Answer:
322.28
A
Step-by-step explanation:
Area of the rectangle
L = 30
W = 21
Area = 30 * 21
Area = 630
Area of the circles
Radius = 7 m
Area = pi r^2
Area = 3.14 * 7^2
Area = 153.86 m^2
Area of both circles = 307.72
Area of the Shaded Region
Area of shaded region = area of the rectangle - area of 2 circles.
Area of Shaded Region = 630 - 307.72
Area of Shaded Region = 322.28
X + y = 1.....multiply by -1
4x + y = -23
---------------
-x - y = -1 (result of multiplying by -1)
4x + y = -23
---------------add
3x = - 24
x = -24/3
x = -8 <====
x + y = 1
-8 + y = 1
y = 1 + 8
y = 9 <====
