Answer 1

Answer:

perimeter is nothing but sum of all the sides

so

1) it's rectangle so formula is 2(l+b)

so 2(9+3)

=2(12)=24cm

2)it is also a rectangle so

substitute in formula

2(6+4)=2(10)=20in

3)this is square so formula is 4s

so 4*7ft = 28ft

4)this is rectangle so answer is

2(10+4) = 2*14 = 28m

5)same for this too as this is rectangle

2(8+7) = 2(15) = 30m

6) this is square again

so 4s

4*2 1/2 so convert into improper fraction

so 4*5/2 = 10cm
