Answer:
A= 160M^2
P=54m
Step-by-step explanation:
L=4CM
B=2.5CM
SCALE=0.5CM =200M
ACTUAL LENGTH = 4/100=0.04M
=0.5/200=0.04/X = 0.04*200/0.5
ACTUAL WIDTH= 2.5/100=0.025m
ACTUAL LENGTH =
=0.5/200=0.04/X = 0.04*200/0.5
=0.5/200=0.04/X = 0.04*200/0.5=8/0.5=16M
- width= 0.5/200=0.025/x
=200*0.025=0.5x
x=5/0.5=10
l=16
b=10
a=l*b
=16*10=160m^2 ans.
p= 2(l+b)
=2*(16+10)
=2*26
=54m ans.
