Question

The length of a rectangle is 5cm more than twice its breadth. If the perimeter of the rectangle is 166cm. Find its dimensions.

Answer 1

Hello mate,

Let the breadth of the rectangle=x

Then its length=2x+5

perimeter of rectangle=166 cm

2(l+b)=166cm

2(2x+5+x)=166cm

2(3x+5)=166 cm

3x+5=166 cm/2

3x=83 -5 cm

x=78cm/3

x=26 cm

So,its breadth is 26 cm

and its length is 2x+5=2*26+5 cm=57 cm

Answer 2

Answer:

Let the breadth of the rectangle=x

Then its length=2x+5

perimeter of rectangle=166 cm

2(1+b)=166cm

2(2x+5+x)=166cm

2(3x+5)=166 cm

3x+5=166 cm/2

3x=83 -5 cm

x=78cm/3

x=26 cm

So, its breadth is 26 cm

and its length is 2x+5=2*26+5 cm=57 cm
