Question

figure efgh gas a perimeter of 40cm and an area of 96sq.cm. it is dilated by a factor of 1/4 to create a figure E' F' G' H

Answer 1

If it’s asking about the new area and perimeter- recall that for a scale factor k, perimeter will change by a scale factor of k while area will change by a scale factor of k^2.

Answer 2

Correct! When you scale a figure or shape by a factor of k, the perimeter will be multiplied by the same factor k, while the area will be multiplied by the factor k^2. This is because the perimeter is a linear measurement and scales proportionally with the factor, while the area is a two-dimensional measurement and scales quadratically with the factor. So, when finding the new area and perimeter after scaling, you would need to apply these formulas to calculate the new values..
