Question

The actual length of side y is 22cm. Use the scale drawing to find the length of side x.

Answer 1

Given:

The actual length of side y is 22cm.

To find:

The length of side x by using the scale drawing.

Solution:

We know that the corresponding sides of original figure and scale drawing are proportional.

`(x)/(1.8)=(y)/(1.4)`

`(x)/(1.8)=(22)/(1.4)`

`x=(22)/(1.4)* 1.8`

`x\approx 28.286`

Therefore, the length of side x is about 28.286 cm.
