Karina is creating two pyramids with the nets below using construction paper. in both nets, all of the triangular faces of the pyramids have a height of 9 inches and a base of 6 inches. compare the amount of construction paper needed to make each pyramid. the triangular pyramid needs square inches of construction paper to make. the square pyramid needs square inches of construction paper to make. the pyramid will need square inches more construction paper to make than the other pyramid.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

c) blue
