Question

The permetre of a rectangle is 66 m. its length is one more than than thrice the breadth. what is the length and breadth ​

Answer 1

Answer:

Let the breadth of rectangular swimming pool be x metres.  

Then, its length =(2x+2) metres.

We know that the Perimeter of a rectangle =2(Length+Breadth)

=2(2x+2+x)=6x+4

According to the given condition, we have  

6x+4=154

⇒6x=154−4           ..[By transposing 4 to RHS]

⇒6x=150

⇒  

6

x

​  

=  

6

150

​  

         ...[Dividing both sides by 6]

⇒x=25  

Thus, breadth =25 m and length =25×2+2=52 m
