Question

10. Find the area of the field whose sides have semi-circular flowerbeds, as given in the
figure:
​

Answer 1

since the sides of the rectangle are 30 m and 42 m so the radii of the semi circles are 15 m and 21 m

now area of semicircles having radius 15m =2×(22/7×15×15)/2

=707.142sq m

and area of semicircles having radius 21m =2×(22/7×21×21)/2

=1386sq m

now total area of the semicircular flowerbeds are

=707.142+1386

=2093.142 sq m

Answer 2

Answer:

2093.142spm

Step-by-step explanation:

15=2*(22/7*15*15)/2

= 707.142spm

21=2*(22/2*21*21)/2

1386spm

707.142+1386

2093.142spm
