a contractor needs to cut a piece of glass to fit a square window. the area of the window is 16 ft^2. find the length of the side window.

Area = 16 ft.²

Use the square root process:

√16

√(4 * 4)

2√4 = 4

4

Step-by-step explanation:

A= L*W (length x width)

16 ft^2= 4*4

           or

x^2= 16

square root (x^2)= x and square root (16)= 4

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
