Question

What is the area of the original rectangle?

Answer 1

It is 8

As a result of multiply 1.6 times 6, we would also need to apply it to the side as well, and therefore multiply it.

Answer 2

ANSWER

$8 {cm}^{2}$

EXPLANATION

First let us determine the scale factor of the enlargement

$k = \frac{image \: length}{corresponding \: object \: length}$

$k = \frac{8}{1.6}$

$k = 5$

This implies that that, the corresponding length of the smaller rectangle is

$l = \frac{25}{5} = 5cm$

The area of the smaller rectangle is

$= 5 \times 1.6 = 8 {cm}^{2}$
