Answer 2

Answer:

Length of the garden: 95 m

Width of the window: 86 cm

Step-by-step explanation:

Part A:

We can use the equation for area to find the length of the garden.

$Area = Width * Length$

If we simply divide both sides of the equation by width, we will be solving for lenght:

$\frac{Area}{Width} = Length$

Now, plug in the known values for the area and width of the garden:

$\frac{6460}{68}=Length$

$95=Length$

Part B:

This time, we'll have to use the equation for perimeter:

$Perimeter = [2(Width)]+[2(Length)]$

Because we want to know the width, and already know the perimeter and length we can once again use algebra to solve for the width:

$Perimeter-[2(Length)] = 2(Width)\\\frac{Perimeter-[2(Length)]}{2} =Width$

Now, simply plug in the values for the perimeter and the length and solve:

$\frac{370-[2(99)]}{2} =Width\\\\\frac{370-198}{2} =Width\\\\\frac{172}{2}=Width\\\\86=Width$

Therefore, the width of the window is 86 cm.
