Question

The lenth of of a rectangular office room is 1m longer than its width if its perimeter is 10m. what are its dimensions?

Answer 1

Let the width be x and lenght be (x+1)m

Now,

Perimeter of rectangle =2(lenght+width)

10=2(x+x+1)

10/2 =x+x+1

5=2x+1

5-1 =2x

4=2x

4/2 =x

2 =x


Now,

Breadth =x=2m


Lenght =x+1=2+1=3m


I hope this will help you

Answer 2

Hey!
let the width of the rectangular office room = x m
so the length becomes= x+1 m
given perimeter= 10 m
A.T.Q
2(l+b) = 10
2(x+1+x)=10
2x+1=10/2
2x+1=5
2x=4
thn x = 2
so the value of x is 2
therefore the width of rectangular office room is 2 m
nd the length is 3 m

this is ur answer...
take care :-)
