Question

the length of a rectangle is 10 metres more than twice its width. what is the length and width of the rectangle if its perimeter is 62 meters

Answer 1

${ \huge{ \boxed{ \bf{\underline{ \red{Answer}}}}}} : -$

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

Answer:

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.
