Question

length and breadth of a rectangular feild is 5:3 . if the breadth of the rectangle is 60 m, find the length of the rectangle.please answer me day after tomorrow my maths exam will held​

Answer 1

Answer:

let , lenght = 5x

breadth = 3x

Perimeter of rectangle = 2 ( l+ b)

= 2 × ( 5x + 3x )

= 2 × 8x

given, = 16x

breadth = 60m

Perimeter of rectangle = 2( l+b ) = 16x

= 2×( 5x + 60 ) = 16x

= 10x + 120 = 16x

= 120 = 16x - 10x = 6x

= 120 = 6x , x = 120/6

= x = 20

length = 5x = 5 × 20 = 100 m

perimeter = 16x = 16 × 20 = 320 m

Answer 2

Answer:

100m

Step-by-step explanation:

Let length be 5x m and breadth be 3x m.

Given, 3x = 60 m

=> x = 60/3

=> x = 20 m

So, length = 5x m = 5× 20 m = 100 m
