Answer 1

Answer:

1)l=12m, b=8m

A=lb=12×8=96m²

P=2(l+b)=2(12+8)=2(20)=40m

2)l=8m, b=250cm=2.5m

A=lb=8×2.5=20m²

P=2(l+b)=2(8+2.5)=2(10.5)=21m

3)l=10m, P=44m

P=2(l+b)

44=2(10+b)

44/2=10+b

22=10+b

b=22-10

b=12m

A=lb=10×12=120m²

4)l=1200cm=12m, A=72m²

A=lb

72=12×b

72=12b

b=72/12

b=6m

P=2(l+b)=2(12+6)=2(18)=36m²
