Question

7) The length of the rectangle is 5 more than twice its breadth. The

perimeter of a rectangle is 52 cm then find the length of the rectangle.​

Answer 1

Step-by-step explanation:

Let the breadth of the rectangle be xcm

Then it's length=x+5cm

Perimeter=2(length+breadth)

⇒52=2(x+(x+5))

⇒ 52/2 =2x+5

⇒2x+5=26

⇒2x=26−5=21

⇒x= 21/2

=1.5cm

Breadth=x=1.5cm and length=x+5=1.5+5=6.5cm

Answer 2

Answer:

Step-by-step explanation:

Let the breadth of the rectangle be xcm

Then it's length=x+5cm

Perimeter=2(length+breadth)

⇒52=2(x+(x+5))

⇒ 52/2 =2x+5

⇒2x+5=26

⇒2x=26−5=21

⇒x= 21/2

=1.5cm

Breadth=x=1.5cm and length=x+5=1.5+5=6.5cm
