Question

12. Find the perimeter of the figure given
alongside. (Use it = 3.14)​

Answer 1

Answer:

perimeter=( 2( 4+ 3) +3.14×2)-4

= (2× 7+6.28)-4

=( 14+6.28) -4

=20.28-4

= 16.28

Answer 2

first find the area of rectangle ABCD

AB=4cm, so

DC=4cm

AD=3cm

BC=3cm

area of rectangle =l×b

perimeter

=(2(4+3)+3.14×2)-4

=(2×7+6.28)-4

=(14+6.28)-4

=20.28-4

=16.28
