Question

A poster is shown below: A rectangle is shown. The length of the rectangle is labeled 18 inches. The width of the rectangle is labeled 6 inches. What are the dimensions if the poster is enlarged by a factor of seven over two ? 42 in by 126 in 3 in by 9 in 9 in by 12 in 21 in by 63 in

Answer 1

Answer:

The dimensions of the enlarged rectangle are 21 in by 63 in

Explanation:

We are given that the length of the original rectangle is 18 in, the width of the original rectangle is 6 in and that the scale factor is $\frac{7}{2}$

To get the new dimensions, we simply multiply the original length by the scale factor as follows:

New length = original length * scale factor = $18 * \frac{7}{2}=63$ in

New width = original width * scale factor = $6 * \frac{7}{2}=21$ in

Based on the above, the dimensions of the new rectangle are 21 in by 63 in

Hope this helps :)
