Question

The length of rectangular field is twice its breadth.If the perimeter of field is 150m.The length is?

Answer 1

let breadth be x
so length 2x
p=2(l+b)
150=2(2x+x)
150=6x
x=150/6
x=25
breadth=25 m
length= 50 m

please follow and thank if u like

Answer 2

Hola ^_^

Given Length of rectangular field= twice the breadth

therefore ,let bread be b
so, length = 2b

perimeter is 150m
====≠========≠=========

to find- The length ?
===≠==========≠============
calculation -
We know Perimeter of Rectangle is 2(l+b)
====≠====================≠=========
Therefore , 2(2b+b)= 150
4b+2b=150

= 6b=150
b= 150/6
= 25

So the length = 2(25)=50m
breadth = 25m

Hope it helps !
