Mr. Daniels

Question

Mr. Daniels wants to cut a square in a wall for a new window. The window is 3 1/8 feet wide. The wall has a length of 15 3/8 feet. Mr. Daniels wants to position the window at the center of the wall.

 

A) How far from each edge of the wall should the window be positioned?

 

B) How can you check that your answer is reasonable?

Answer 1

The height of the wall is not given. So, in order to solve this question, it is necessary to assume that the wall is a square, otherwise there is no way to find its center.

 

To make the solution easier, we will convert the fractions into decimals. So, 3f1/8in = 3.125f, and 15f3/8in = 15.3.75f 

 

But, assuming a square wall 15.375f by 15.375f, its center will be 15.375f ÷ 2 = 7.6875f from an edge

 

So, all that needs to be done is to place the center of the window at the center point of the wall. The center of the window will be 1.5625f from one of its edges.

 

A reasonable check can be made by using graph paper to draw a model of the installation.
