Question

if the perimeter of a field is 20 m and its breadth is 4 m find its length

Answer 1

Perimeter of a field/rectangle=2(l+b)

Breadth(b)=4m

Perimeter=2(l+b)

20=2(l+4)

10=l+4

6=l

Therefore length l=6m

Hope this helps you.

Answer 2

hey mate


Here's your answer

Perimeter of Rectangle = 2( L + B )


Perimeter of the field = 20 m
Breadth = 4 m


Let length be L

2 ( L + B ) = Perimeter of rectangle
2 ( L + 4 ) = 20
2L + 8 = 20
2L = 20 - 8
2L = 12
L = 12/2
L = 6 m
