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.
