The new perimeter of the rectangle if the dimensions are quadrupled would be 72 inches.
<h3>What are the side lengths of the first triangle?</h3>
The perimeter is always obtained by adding all the sides. This means the possible side lengths of the original rectangle are:
- 5 inches + 5 inches + 4 inches + 4 inches
<h3>What are the side lengths of the new triangle?</h3>
5 inches x 4 = 20 inches
4 iches x 4 = 16 inches
<h3>What is the new perimeter?</h3>
20 + 20 + 16 +16= =72 inches

You need to do 6*3=18
Then x*y= xy
Let the numbers be x and y, then
2x + y = 47 . . . (1)
x + 3y = 56 . . . (2)
(2) x 2 => 2x + 6y = 112 . . . (3)
(1) - (3) => -5y = -65 => y = -65/-5 = 13
From (2), x + 3(13) = 56 => x = 56 - 39 = 17
The two numbers are 13 and 17.
It is impossible to solve for both variables without a second equation.
