15..) side of square =35 m
perimeter of square = 4x side= 35x4=140m
now cost of fencing = 140x 40=5600 rupees..
16) l=12cm ,b=9cm
now perimeter of rectangle = 2(l+b)=2(12+9)=42m
now perimeter of rectangle = perimeter of square
therefore perimeter of square =42m
4xside=42
side=42/4=10.5m
17) circumference of circle= 57.2
2pie r=57.2
2x22/7 x r=57.2
r= (57.2x 7)/44
r=400.1/44=9.1 ans

R = 57.2 ÷ 2 × Pi
= 57.2 × 7 ÷ 2 × 22

your ans is correct and you are a genius
but i had make veera has make brainlest because he has ans first but dont be sad you are also a genius and your ans is correct
