Which formula should be used to find the area of the composite shape?

The last option seems the best one: the figure is composed of a square/rectangle and a triangle. The area of the rectangle is the product of its dimension (i.e. ), while the area of the triangle is half the product of the base and height ().

The sum of the two areas is the area of the composite shape.

the last choice

step-by-step explanation:

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.
