What is the area of the new trapezoid formed by dilating the original by a factor of 3

Step-by-step explanation:

The are of a trapezoid is:

where:

When a geometric figure dilates, every coordinate of the original figure must be multiplied by the scale factor of this dilatation. In our case this factor is 3, therefore we will have:

The new area is 9 times the original one.

0 is its x and y coordinate

lockers 1, 4, 9, 16, 25, 40, and 49 are open
