The floor area ratio is calculated by taking the square footage of a building and dividing it by the square footage of the property that the building sits on. The floor area ratio is useful to local governments in showing the density of a property or area for zoning decisions.
Know MoreThe square footage of the building includes all floors of the structure when calculating the floor area ratio. For example, a two-story building of 3,000 square feet on a 4,000-square-foot lot has a ratio of 0.75. The same lot with a single-story building of 3,000 square feet would have the same ratio of 0.75.
Learn MoreThe area of a parallelogram can be calculated by multiplying the length of the base by the height to the top, perpendicular to the base. Either edge on either set of sides can be oriented to be the base. The formula for a parallelogram's area is similar to that of a rectangle, because a rectangle is a special type of parallelogram.
Full Answer >The grade percentage is calculated by dividing the rise over run and by multiplying the result by 100 percent. In other words, the change in vertical distance divided by the change in horizontal distance times 100 percent gives the grade percentage.
Full Answer >To find the area of a triangle without a right angle, you multiply one-half the base by the height. Obtuse triangles are included in this group.
