Question

The dimensions of the scale drawing of a rectangle are 8cm and 11cm. If the scale factor is 4, what is the length of the original rectangle?

Answer 1

Length of the original rectangle is 2.75 cm

Explanation:

The dimensions of the scale drawing of rectangle are 8 cm and 11 cm respectively.

This implies that the width of the rectangle is 8 cm while the length of the rectangle is 11 cm.

The scale factor is given as 4. This means that the dimensions of the original rectangle are 1/4 times the given dimensions.

So the length of the original rectangle =
`\[(1)/(4)*11\]`

=
`\[2.75\]`
