The breadth of a rectangular plot of a field is 100 m less than its length. if it's perimeter is 1400 m,find the area of the fie ld?
1 answer:
Answer:
Length=400m
Breadth=300 m
Explanation:
Let the length be( x+100) and breadth be x
Now,
Perimeter of rectangle = 2(l+b)
or, 1400 m= 2(x+100m+x)
or, 1400m/2=2x+100m
or, 700 m-100m= 2x
or, 600m/2 = x
Therefore x= 300m
(x+100m)=300m + 100m = 400m
