Answer 2

Answer:

12. 32m

13. 55m

Step-by-step explanation:

12. Perimeter of a rectangle is 2(length+breadth).

so if length is 50 metres, and perimeter is 164 metres, then

2(50+b)=164m

50+b=82m

b=82-50=32m

breadth=32m

13. In the same way, (here the length of the previous question is the breadth)

2(27+l)=164m

27+l=82m

l=82-27=55m

length=55m
