Question

Find the AREA AND PERIMETER of the figure below. Take pi= 3.14
(Please help me)

Answer 1

Answer:

area of figure= 49.2075

perimeter of figure= 12.87

Step-by-step explanation:

the given figure is formed when,

semicircle with radius 4.5m is been cut from a square with side 9m.

therefore,

area of square is 81 & perimeter of square is 36.

area of semicircle is 31.7925 & perimeter of semicircle is 23.13.

hence,

area of given figure = area of square - area of semicircle

area of given figure = 81 - 31.7925

area of given figure = 49.2075

also,

perimeter of given figure = perimeter of square - perimeter of semicircle

perimeter of given figure = 36 - 23.13

perimeter of given figure = 12.87
