Question

4. The length of a rectangle is 10 meters more than twice its width. What is the length and width of the rectangle if its perimeter is 62 meters.

Answer 1

Let the breadth be p
Then length will be 2p +10

So perimeter =2( p + 2p + 10) =2( 3p +10)

=6 p + 20

Given perimeter =62 m

6p +20=62

6 p =62-20

6p =42

p =42/6=7

Therefore, Length is 24 cm, Breadth =7 cm.

Answer 2

length is 24cm and width is 7 cm
