Question

You’re building a rectangular frame 10 inches by 11 inches. How many feet of wood do you need?

Answer 1

Answer:

The required feet of wood needed is 3.5 foot.              

Step-by-step explanation:

Given : You’re building a rectangular frame 10 inches by 11 inches.

To find : How many feet of wood do you need?

Solution :

According to question,

We have to find the perimeter of the rectangle,

The perimeter of the rectangle is

$P=2(L+W)$

$P=2(10+11)$

$P=2(21)$

$P=42inches$

The perimeter of the rectangle is 42 inches.

Which means the wood required is 42 inches.

Convert inches into feet,

1 foot = 12 inches.

1 inch = $\frac{1}{12}$ foot.

42 inches =  $\frac{42}{12}$ foot.

42 inches = 3.5 foot.

Therefore, The required feet of wood needed is 3.5 foot.

Answer 2

The problem above is simply asking for the perimeter of the frame. Perimeter is the sum of all side lengths of a shape. For this we have a rectangular shape therefore perimeter is calculated as:

P = 2l + 2w = 2(11) + 2(10) = 42 inches
P = 42 inches ( 1 ft / 12 inches ) = 3.5 feet of wood is needed for the frame
