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.
Let the width of the storm window be ( w ) inches. Since the window is 6 inches higher than it is wide, the height can be expressed as ( w + 6 ) inches. The area of the window can be calculated using the equation ( w(w + 6) = 315 ). This equation can be used to find the dimensions of the window.
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.
Let the width be ( w ) inches and the height be ( h = w + 6 ) inches. The area of the storm window can be expressed as ( w \times h = 315 ) square inches. Substituting for ( h ), we have ( w(w + 6) = 315 ). Solving this gives the width ( w \approx 15 ) inches and height ( h \approx 21 ) inches.
Let the height of the window be ( h ) inches. Then the width would be ( h + 12 ) inches. The area of the window can be expressed as ( w \times h = (h + 12) \times h = 400 ). Solving the equation ( h^2 + 12h - 400 = 0 ) gives the dimensions; the height is approximately 8 inches and the width is approximately 20 inches. Thus, the dimensions are 20 inches wide by 8 inches high.
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
To determine the dimensions of the window opening itself without the frame, subtract twice the frame width from each dimension of the window. The width would be 25 inches - 2 inches (left frame) - 2 inches (right frame) = 21 inches. The height would be 32 inches - 2 inches (top frame) - 2 inches (bottom frame) = 28 inches. Therefore, the dimensions of the window opening are 21 inches by 28 inches.
The area of the window is 21.8 square feet.
The window seat bench measures 48 inches in length, 18 inches in width, and 20 inches in height. It has a weight capacity of 300 pounds.
Well, isn't that a lovely question! To find the length of the window, we can use the formula for the area of a rectangle, which is length times width. Since we know the area is 336 square inches and the width is 16 inches, we can divide the area by the width to find the length. So, the window is 21 inches long. Happy little calculations!
You have to multiply the two dimensions to get the area. In this case the answer will be 15 square feet.
