Simply add the numbers up

For example, If the area of a semicirce is 20cm squared and the area of a rectange is 25cm squared, then the total area would be 20 + 25 = 45

How do you find the area of a rectangle with a semi circle attached to it?

Calculate the area of a rectangle and of the semicircle separately, then add.

A Norman window has the shape of a semicircle atop a rectangle so that the diameter of the semicircle is equal to the width of the rectangle. What is the area of the window with a perimeter of 45 feet?

To find the area of the Norman window, you need to divide the perimeter by 2 to get the width of the rectangle, which is 22.5 feet. The radius of the semicircle is half of the rectangle's width, so it's 11.25 feet. The area of the rectangle is 11.25 * 22.5 = 253.13 square feet, and the area of the semicircle is 0.5 * pi * 11.25^2 = 198.93 square feet. So, the total area of the window is 253.13 + 198.93 = 452.06 square feet.

These windows could get extremely large, but let's play with Andersen Windows' catalog. If you build a Norman window using Andersen's largest semicircle window, which is six feet wide, and their tallest twin double-hung window, which is 6'4" high, you get an area of 52.11 square feet.

What is the equation to solve the area of a semicircle?

Area of a semicircle = (pi*radius^2)/2

A Norman window has the shape of a semicircle atop a rectangle so that the diameter of the semicircle is equal to the width of the rectangle. What is the area of the largest possible Norman window with a perimeter of 45 feet?

To solve this problem, let's break it down step by step. Let ( r ) be the radius of the semicircle, which is also the width of the rectangle. The perimeter of this figure (Norman window) is given as 45 feet: The perimeter, ( P ), is the sum of the parts: the semicircle's circumference and the perimeter of the rectangle. The semicircle's circumference: ( \pi r ) The perimeter of the rectangle: ( 2r + 2r = 4r ) So, the total perimeter equation is: [ \pi r + 4r = 45 ] This simplifies to: [ \pi r + 4r = 45 ] [ (\pi + 4) r = 45 ] [ r = \frac{45}{\pi + 4} ] Now, we need to find the total area of the figure. The area of the semicircle is: [ \frac{\pi r^2}{2} ] The area of the rectangle is: [ r \times 2r = 2r^2 ] The total area, ( A ), is the sum of these two parts: [ A = \frac{\pi r^2}{2} + 2r^2 ] Substitute the value of ( r ) derived earlier: [ A = \frac{\pi (\frac{45}{\pi + 4})^2}{2} + 2(\frac{45}{\pi + 4})^2 ] Calculating this would give the area of the largest possible Norman window with a perimeter of 45 feet.
