Question

a perimeter of rectangular field is 250m .if its length is 75 m find its area

Answer 1

hey here is the answer
as we know perimeter of reactangle=2(l+b)
given perimeter =250m
length=75m
now,2(l+b)=250
2(75+b)=250
75+b=250÷2
75+b=125
b=125-75
b=50

now area=l×b
75×50
Ans=3750m^2

Answer 2

Perimeter= 250cm
Length= 75cm
P= 2 (l +b)
=>250=2 (75+b)
=>250=150+2b
=>250-150=2b
=>100=2b
=>100/2=b
=>50=b
Breadth =50cm
Area=length×breadth
Area=75cm×50cm
Area=3750cm2
