Question

the lenght of rectangular garden 5 m more than twicw its breadth if its perimeter is 100 m find its deminons​

Answer 1

Answer:

Given Length is 5 more than twice its breadth

and perimeter=100 m

Let the breadth be x

Let the length be 2x+5

We know

perimeter of a rectangle=2(l+b)

where

l= length

b= breadth

substituting the Values

that is

2((2x+5)+x)=100

4x+10+2x=100

6x+10=100

6x=100-10=90

x=90/6

x=15

therefore

breadth=x=15 m

length=2x+5=2×15+5=35

Let's check whether it's correct or not

that is

2(35+15)=100

2×50=100

100=100

L.H.S=R.H.S

hence verified

hope it helps
