A piece of paper is to display ~150~ 150 space, 150, space square inches of text. If there are to be one-inch margins on the sides and the top and a two-inch margin at the bottom, what are the dimensions of the smallest piece of paper that can be used?.

Respuesta :

The paper's smallest dimensions are height=8.660in and width=17.321in.

What are dimensions?

In physics and mathematics, the dimension of space is the smallest set of coordinates needed to specify any point within a mathematical space.

A line has a dimension of one because only one coordinate is needed to specify a point on a line, such as a point at 5 on a number.

So, we have:

Area = 150in²

Side margin = 1 in

Top and Bottom Margin = 2 in

To obtain the smallest dimensions, calculate as follows:

The printed material's area is:

Area = l*w

A1 = h*w

A1 should be changed to 150:

150 = h*w

h = 150/w

The complete paper's topic is:

Area = l*w

A2 = (w+2+2)*(H+1+1)

A2 = (w+4)*(H+2)

For H, substitute 150/W:

A2 = (w+4)*(150/w+2)

A2 = w(150/w+2) + 4(150/w+2)

A2 = 150 + 2w + 600w + 8

A2 = 2w = 600/w + 8 + 150

A2 = 2w = 600/w + 158

Calculate a difference with regard to w and set the outcome to 0:

A'2 = 2-600/w²+0

A'2 = 2-600/w²

0 = 2 - 600/w²

2 = 600/w²

2*w² = 600

w² = 600/2

w² = 300

w = 17.321

Remember that:

h = 150/w

h = 150/17.321

h = 8.660

Therefore, the paper's smallest dimensions are height=8.660in and width=17.321in.
