Answer 1

Answer:

Step-by-step explanation:

2(25+15)=80-----1st eq.

After increase 2 m in each side

2(27+17)=88-----2nd eq.

2nd eq.- 1st eq.

88-80=8

8 m increase in perimeter before increaseing

Answer 2

Answer:

the new perimeter will increase by 8 cm

Step-by-step explanation:

perimeter =2×(l+b)

=2×(25+15)

=2×40

new perimeter=2×(27+17)

= 2×44

= 88 m

therefore the ratio is 80:88

= 10:11
