A Norman window is a window with a semi-circle on top of regular rectangular window. (See the picture.) What should be the dimen

grin007 [14]

Answer:

length = 4 feet, and width = 2 feet

Step-by-step explanation:

Given that 12 feet of the frame material is available for the rectangular part of Norman's window. Then,

Perimeter = 2 (length + width)

Perimeter of the frame = 12 feet

So that,

Perimeter = 2 (length + width)

12 = 2 (length + width)

length + width = $\frac{12}{2}$

length + width = 6 feet

Therefore, to allow much light as possible, the dimensions of the window would be; length = 4 feet, and width = 2 feet.
