Question

The ration between the length and width of rectangular field is 7:5 if the width is 20.5cm find its length

Answer 1

Answer:

28.7

Step-by-step explanation:

let length be 7x and width be 5x

given width = 20.5

therefore 5x = 20.5= 4.1. ...... because width is 5x

therefore X= 4.1

now length = 7x .....given

therefore 7 × 4.1 = 28.7

therefore length = 28.7
