Question

Find the perimeter of following shapes to 1 decimal place ( take π= 3.14 or 22/7)

Answer 1

Answer:

88.24 cm

Step-by-step explanation:

the radius would be 8 cm that can be seen from the fig.

so, r=8 cm

there are 2 semi circles whose radii are same.

the formula for perimeter of semi circle is pi r

the formula for perimeter of rectangle is 2(l+b)

here l=16 cm and b=3 cm

perimeter(P)= pi r +2(l+b) +pi r

P= 3.14*8 + 2(16+3) + 3.14*8

P= 88.24 cm

Answer 2

Answer:

ans of this question is 53.7 cm
