Question:

Solution:

The perimeter of a rectangle is the sum of the lengths of its sides. According to this, we get the following equation:

$P\text{ = 2(4y+2)+2(5y)}$

since P = 112, we obtain:

$112\text{ = 2(4y+2)+2(5y)}$

Applying the distributive property, we obtain:

$112\text{ = 8y+4+10y}$

this is equivalent to:

$18y\text{ = 112-4}$

that is:

$18\text{ y = 108}$

solving for y, we get:

$y\text{ = }(108)/(18)=6$

that is:

$y\text{ = 6}$

so that, we can conclude that the correct answer is:
