Question

A rectangle has a length of 11 inches and a width of 8.5 inches. This rectangle is dilated by a scale factor of 2.2 to create a new triangle. Which figure represents the new triangle?

Answer 1

The new rectangle is
L = 11 * 2.2 = 24.2
W = 8.5 * 2.2 = 18.7

Answer 2

The dimensions of the new rectangle are
`24.2\ in` by
`18.7\ in`

Explanation:

we know that

The dimensions of the new rectangle will be equal to the dimensions of the original rectangle multiplied by the scale factor

In this problem we have that

the scale factor is equal to
`2.2`

so

Find the new length L2

`L2=11*2.2=24.2\ in`

Find the new width W2

`W2=8.5*2.2=18.7\ in`
