Question

Find the Perimeter of the figure below, composed of a parallelogram and one semicircle. Rounded to the nearest tenths place

Answer 1

Add all perimeter

P=6+14+14+1/2 pi (6)

Evaluate

Solution

P=43.4

Answer 2

43.4

Explanation:

Perimeter = sum of the lengths of the sides

Circumference of circle = πd

Circumference of semicircle = (1/2)πd

Top side: 14

Left side: 6

Bottom side: 14 (opposite sides of a parallelogram are congruent)

Semicircle: (1/2)πd = (1/2)π(6) = 3π = 9.4

perimeter = 14 + 6 + 14 + 9.4

perimeter = 43.4
