Question

The length of a rectangle is 3 more days than than twice its width. The perimeter of the rectangle is 42 centimeters. What is the length of the rectangle​

Answer 1

Solution:

It is given that length of a rectangle is 3 more days than than twice its width. The perimeter of the rectangle is 42 centimeters.

So,

• Perimeter of Rectangle = 42 cm

Let Required Breadth of Rectangle be x

• Then, Length of Rectangle = 2x + 3

Now, We have ;

Perimeter of Rectangle = 2(l+b)

Perimeter of Rectangle = 2(2x+3+x)

42 = 2(3x+3)

42 = 6x + 6

42 - 6= 6x

36= 6x

x = 6 cm

• So, Length of Rectangle = 2x + 3

Length of Rectangle = 2(6) + 10

Length of Rectangle = 22 cm
