Question

Find the perimeter correct to 1 decimal place Take pi 22/7

Answer 1

Circumference of big semi-circle =2πr₁/2=πr₁

=3.14×4=12.96cm

Circumference of small semi-circle =2πr₂/2=πr₂

=3.14⨯2=6.28cm

length of both sides =3+3=6cm

length of side left of rectangle=4cm

total perimeter=6+4+6.28+12.96=29.24cm

so perimter of figurebis 29.24cm
