Answer 2

Q6.

Perimeter of the square= 75*4=300m

Rate of fencing =4/m

Hence, 

Total cost of fencing is= 300*4=Rs.1200.

Q7.

side of square=30m

perimeter of square=length of rope required to fence

perimeter of square=side×4=30×4=120m

therefore length of rope required to fence =120m+2m=122m.

Q8.

Here the side of equilateral triangle is X=16cm

Hence, total length of wire = perimeter of triangle

= X+X+X =3X =3(16) = 48 cm

Now wire is bent in shape of octagon.

Let, the side of octagon is Y cm.

Hence, perimeter of octagon

= total length of wire

So, 8Y=48

Y=48/8 =6cm

Hence length of side of octagon is 6 cm.

Q9.

perimeter=56

each side=56/4

=14

half of each side=14/2

=7

perimeter=7×4

=28 cm

Q.10

perimeter of rectangle is 2×(12+6)

=36cm

60-36=24cm(other part of rope)

hexagon side=6

24/6=4cm each side

hope it helps u
