Question

The ratio of the length and the width of a rectangular sheet of paper is 8:5. If the width of the sheet is 17.5 cm ,find its length.​

Answer 1

Answer:

28 cm

Step-by-step explanation:

let it's length be =x

and width be=y=17.5 cm

then a/q,

x:y=8:5

x/y=8/5

x/17.5=8/5

x=8×17.5/5

x=140/5=28 cm

Answer 2

Answer:

28 cm

Step-by-step explanation:

Given:

• Width of the rectangular sheet of paper = 17.5 cm
• Ratio of the length and width of the rectangular sheet of paper = 8:5

To find:

• Length of the rectangular sheet of paper

let the length be equal to 8x and width be equal to 5x

according to the question:

5x=17.5

x = 17.5/5

x = 3.5

Length = 3.5×8

Length = 28 cm

The length of the rectangular sheet of paper is equal to 28 cm
