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

Solution:

Given, rectangular frame building 10 inches by 11 inches.

Let us take length as 11 inches and breadth as 10 inches.

We have to find the required feet of wood needed to build the frame.

Thus, we have to find the perimeter of the rectangular frame.

Perimeter of a rectangle = 2(length + breadth)

P = 2(11 + 10)

= 2(21)

= 42 inches

Now converting inches to feet,

1 foot = 12 inches

So, 1 inch = 1/12 foot

So, 42 inches = (1/12)(42)

= 42/12

= 21/6

= 7/2

= 3.5 foot

Therefore, the required wood is 3.5 feet
