A+ x(x-6)=315
Mr.Lumen replaced a square window with a rectangular one. the new window is 3ft wider and 2ft higher that the square one. it has an area of 30ft2 . How long was aside of the original square window?
Area A = 1/2 base b time height h b = 2A/h = 270/15 = 18 inches
1044 sq. inches
Perimeter = (2 lengths) + (2 heights)2 (2x+2) + 2(6x) = 4x + 4 + 12x = (16x + 4) inches
height of a building firemen , construction workers and other workers often rely on the use of ladders in their line of work . for ex the height to a second story window may be 25 feet and a window cleaner may need to put the ladder ten feet away from the building in order to avoid bushes. so for this task the window cleaner will need a ladder this feet long - 25^2 + 10^2 = C^2 625 + 100 = 725 square root of 725 is 27 so the window cleaner would need a ladder 27 feet long.
Measure the height and width of the window in inches. Next, multiply the height of the window by the width of the window. Then divide that number by 144 to get square feet.
H = W + 20; H x W = 640 ie W x (W + 20) = 640 ie W^2 + 20W - 640 = 0 This does not have a solution in integers, a close approximation is 17.2 x 37.2
The are of a window is 16 inches wide how long is the window
The area of the window is 21.8 square feet.
You have to multiply the two dimensions to get the area. In this case the answer will be 15 square feet.

area = width times height x = height x-12 = width x (x-12) = x^2 - 12X = 400 x^2 - 12X - 400 = 0 solve for x using quadratic formula X = (12 + SQRT(144 + 1600)) divided by 2 x = 26.88 = height width = x -12 = 14.88

A car doors dimensions can be a lot of things depending on the make and model of a car. Generally a car door is at least five feet square if you count the window also.
