One side of a triangle is 15 inches, and the area of the triangle is 90 sq. inches. find the area of a similar triangle in which the corresponding side is 9 inches.

207/8 is the right

what shape is

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )

if i did my math right then the answer should but 108
