A carpenter is framing a window with wood trim where the length of the window is 6 2/3 feet. If the width of the window is 7 3/4 feet, how many feet of the wood is needed to frame the window?

Respuesta :

we know that

shape of window is rectangular

We are given

length of window is

[tex] l=6\frac{2}{3} =\frac{20}{3} [/tex]

width of window is

[tex] w=7\frac{3}{4} =\frac{31}{4} [/tex]

For finding amount of wood , we have to find perimeter

[tex] perimeter=2(l+w) [/tex]

[tex] perimeter=2(\frac{20}{3}+\frac{31}{4}) [/tex]

[tex] perimeter=\frac{173}{6} [/tex]

so, the amount of wood is

[tex] =\frac{173}{6}feet [/tex]............Answer
