what is the max number of isosceles right triangles whose legs are 3 inches long that can be cut from a rectangular sheet of paper measuring 14 x 10 inches.
a. 12
b. 15
c. 24
d. 30
e. 31
so 1. how do you do this problem?
2. why can't i compare areas? like the way i did it below....
my way: i compared areas: area of rectangular sheet/area of triangle
140/(.5) (3)(3)=140 (2/9) = approximately 15 x 2=30 this is under approximation so I choose E as the answer
answer to problem: C: 24
instead, kaplan compared sides 14/3 =4 and 10/3= 3 4x 3 =12 so if you double this you get 24 if you think about 2 isosceles =1 square.
