Use the formula for the area of a trapezoid a=h((b1+b2)/2), where a is area, b1 and b2 are the length of the bases, and h is the height, to answer the question. how many square feet of grass are there on a trapezoidal field with a height of 75 ft and bases of 125 ft and 81 ft? hint: plug in the given values for h, b1, and b2.

The grass on the trapezoidal field is  7,725 ft².

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs

Area of a trapezoid = 0.5  x (sum of the lengths of the parallel sides) x height

0.5 x (125 + 81) x 75

0.5 x 206 x 75 = 7,725 ft²

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
