A rectangle on a coordinate plane has a length of 5 units and a width of 3 units. If the rectangle is dilated by a scale factor of 5, what is its new area?(1 point)

Question

square units

Answer 1

The original area of the rectangle is 5 units x 3 units = 15 square units.

When the rectangle is dilated by a scale factor of 5, both the length and width will be multiplied by 5.

The new length of the rectangle is 5 units x 5 = 25 units.
The new width of the rectangle is 3 units x 5 = 15 units.

Therefore, the new area of the rectangle is 25 units x 15 units = 375 square units.
