Question

find the perimeter of this figure​

Answer 1

Answer:

87.69 m

Step-by-step explanation:

given,

length = 17 m

breadth = 5 m

perimeter = 2( l+b )

= 2( 17 +5 )

= 2*22

= 44 m

and also given,

diameter of the semicircle = 17 m

so,

perimeter of the semicircle = 1/2 (πd) + d

= 1/2 ( 3.14*17 ) + 17

= 1/2*53.38 +17

= 26.69 +17

= 43.69 m

so now the perimeter of the figure = 44 m + 43.69 m

                                                          = 87.69 m

THEREFORE, THE PERIMETER OF THE FIGURE = 87.69 m
