The semicircle has diameter 18 ft, so it has radius 9 ft, and this is the height of the rectangle.

The area of the shaded region is (area of rectangle) - (area of semicircle).

The area of a circle with radius is , so the area of a semicircle with the same radius is , and in this case that's .

The area of the rectangle is .

Then the area of the shaded region is

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:
