Let x equal the one number.
Let y equal the other number.
x + 3y = 24
5x +3y = 36
Subtract the first equation from the second equation.
4x = 12
x = 3
To answer this you will use the formula for finding area of a parallelogram.
A = bh
3 inches x 2 inches
A = 6 square inches per piece of paper
6 square inches x 15 = 90 square inches
90 in.² of paper is used to make 15 pieces.
