What is the area of a square that has a length of 55 and a width of 45?
this is not a square, but a rectangle, first off. second, the rectangle's area is 2475 square feet.
How to compute the area to know how much tons of refrigeration is needed?
I assume your formula is based on interior square feet of building area. If the building is a rectangle or square, then the length in feet, multiplied by the width, in feet, gives you the total area, in square feet. If the building is square, the length and width are both the same length. Measure the lengths and widths in feet and tenths of feet, or if allowed, round off to the nearest foot. If you use inches, convert them to feet and tenths of feet, or if allowed, round off the tenths of feet to the nearest foot. If the building has more than four sides, draw lines inside the building, to divide the interior building shape into two or more rectangles. Calculate the area for each rectangle and add up the areas from each rectangle, to get the total square feet or total area of the building.
How do you find the unknown height of a trapezoid if the bases are 27cm and 31 cm and the area is 348cm2?
You can cut the tapered ends off of the trapezoid, and calculate the individual areas of the three pieces. The center piece is a rectangle, Length = 27, Height = H. Area = 27H. Each end is a triangle, Base = 2, Height = H. Area = (1/2 base) times (height) = 1H (Left-end triangle) + (center rectangle) + (right-end triangle) = 1H + 27H + 1H = 29H. 29H = 348 cm2 H = 348/29 = 12 cm
How do you calculate surface area of a plenum?
A plenum is a meeting area where all participants are in attendance - as opposed to splitting off into small groups. Its size will depend on the number of people attending.
