Question

The diagram represents the enlargement of a rectangle by using a scale factor of 6.

Answer 1

Answer:

The dimensions of the original rectangle are 5 feet by 1 foot

Step-by-step explanation:

Let the x be the original length

let y be the original breadth

We are given that the enlargement of a rectangle by using a scale factor of 6.

So, Enlarged length = 6x

Enlarged breadth = 6y

We are given that A rectangle has a length of 30 feet and width of 6 feet.

Enlarged length = 6x = 30

$x=\frac{30}{6}$

x=5

Enlarged breadth = 6y=6

$y=\frac{6}{6}$

y=1

Hence the dimensions of the original rectangle are 5 feet by 1 foot

Answer 2

Please consider the attached file.

We can see from attachment that sides of original rectangle are smaller than sides of new rectangle.

The new rectangle has a length of 30 feet and width of 6 feet.

To find the the length of original rectangle, we will divide sides of new rectangle by scale factor (6).

$\text{Length of original rectangle}=\frac{30\text{ ft}}{6}$

$\text{Length of original rectangle}=5\text{ ft}$

$\text{Width of original rectangle}=\frac{6\text{ ft}}{6}$

$\text{Width of original rectangle}=1\text{ ft}$

Therefore, the dimensions of original rectangle are 5 feet by 1 foot and option A is the correct choice.
