Question

joe wants to make a scale drawing of a flower for mrs Samuelson.she wants him to use a scale of 2 cm:5in. If the flower is 8 in height in real life, how high should he make his drawing?

Answer 1

The needed scale is 2 cm:5in

It means that 2 cm will represent 5 inch of actual flower. if the flower of 8 inch would be in real the required equation would be:

2cm = 5 inch

xcm= 8 inch

X representing height of flower.

After Cross Multiplying,

2 × 8 = x × 5

`x = (2 * 8)/(5) \\ \\ x = (16)/(5) \\ \\ x = 3.2`

The Height Of the tree required is 3.2 cm

Hope This Helps You ❤️

Answer 2

The required scale is 2 cm t 5 in

This means that 2cm on the drawing would represent 5 inches on the actual flower. If the flower is 8 inches in real life, then the equation would be as shown below

2cm = 5 in

xcm = 8 in

where x represent the height of the flower on the drawing. By cross multiplying, we have

x * 5 = 2 * 8

5x = 16

x = 16/5

x = 3.2

The height of the tree on the drawing would be 3.2 cm
