Answer:

Step-by-step explanation:
The initial dimensions of the paper are:
(length)
(width)
After the paper is cut along the diagonal, we remain with a right triangle, of which the length and the width corresponds to the base and the height.
For a triangle, the area is calculated as

where
b is the base
h is the height
Here we have:

Therefore, the area of the triangle is:

4x + 2y = 5y + 7
4x - 3y = 7
4x - 3y = 7
8x + 3y = 41
----------------add
12x = 48
x = 48/12
x = 4
8x + 3y = 41
8(4) + 3y = 41
32 + 3y = 41
3y = 41 - 32
3y = 9
y = 9/3
y = 3
solution is (4,3)
Answer:
a = 8 and b = 5
Step-by-step explanation:
A - B = 3
A + B = 13
2A = 16
A = 8
8 - B = 3
B = 5
