Find area and perimeter of shaded regions below

Step-by-step explanation:

ABCD is a square.

side = 24 cm

Area of square = side  * side = 24 * 24 = 576 cm²

Semicircle:

d = 24 cm

r = 24/2 = 12 cm

Area of semi circle =πr²

                               = 3.14 * 12 * 12

                               = 452.16 cm²

Area of shaded region = area of square - area of semicircle  + area of semicircle

  = 576  - 452.16 + 452.16

  = 576 cm²

Perimeter:

Circumference of semicircle = 2πr

               = 2 * 3.14 * 12

               = 75.36

Perimeter = 2* circumference of semicircle + 24 + 24

                = 2 * 75.36 + 24 + 24

                = 150.72 + 24 + 24

                 = 198.72 cm

Step-by-step explanation:

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

2x+1=10−x

Step 1: Simplify both sides of the equation.

2x+1=10−x

2x+1=10+−x

2x+1=−x+10

Step 2: Add x to both sides.

2x+1+x=−x+10+x

3x+1=10

Step 3: Subtract 1 from both sides.

3x+1−1=10−1

3x=9

Step 4: Divide both sides by 3.

3x/3=9/3

x=3
