<u><em>The question in English is</em></u>
A rectangular window is l meters wide and h meters high, with a perimeter of 6 meters and an area of 2m². What is the formula for calculating the width of the window?
we know that
The perimeter of the window is equal to
we have
so
simplify
isolate the variable l
----> equation A
The area of the window is equal to
we have
so
----> equation B
substitute equation A in equation B
solve for w
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
---> formula for calculating the width of the window
