Question

The perimeter of a rectangle is 40m. The length of the rectangle is 4m less than 5 times its breadth. Find the length of the rectangle

Answer 1

Answer:

32.67 m

Step-by-step explanation:

Given perimeter = 40 m

Let the breadth be x

Therefore length = 5x - 4  (according to condition)

Perimeter = length + breadth

Inserting values,

40 = x + 5x - 4

40 = 6x - 4

44 = 6x

Therefore x = 44/6 , ie : Breadth = 44/6 m

Therefore length = 5x - 4 = 5*(44/6) - 4 = 32.67 m

Hope u will get it friend!

Answer 2

Given perimeter = 40 m

Let the breadth be x

Therefore length = 5x - 4  (according to condition)

Perimeter = length + breadth

Inserting values,

40 = x + 5x - 4

40 = 6x - 4

44 = 6x

Therefore x = 44/6 , ie : Breadth = 44/6 m

Therefore length = 5x - 4 = 5*(44/6) - 4 = 32.67 m
