A triangle can't have two right angles because there is 180° in a triangle. Each right angle is 90° so it would be impossible
A = bh/2
12= bh/2
bh = 24
We need to find pairs that multiply to 24
Answer: b=3 and h=8
, b=6 and h=4, b=12 and h=2
Since the length is 15, and the width would be 15, you need to first do 15 x 15.
15 x 15 = 225
Multiply the 6 faces.
225x6
Your final answer would be 1,350.
63 = 9k
divide by 9 on each side to get k by itself
k = 7
