between the two bases or in other words lies on the median of trapezoid. A trapezoid is a 4 sided polygon

that has at least one pair of sides parallel. For a given trapezoid that has parallel side a and b where the b is

the base and height is h and Centroid is above b at a distance of x the formula for Centroid is given by:

X = [(2a + b) / (3 x (a + b))] x h

3 m.

Base length a=4 m; b=2 m

Height h = 3 m

Centre of the trapezoid X = [(2a + b)/(3 x (a + b))] x h

X = [(2a + b)/(3 x (a + b))] x h

X = [(2(4) + (2))/(3 x ((4) + (2)))] x 3

X = [10/18] x 3

X = 1.66 m

m.

Base length a=3 m; b=5 m

Height h = 2 m

Centre of the trapezoid X = [(2a + b)/(3 x (a + b))] x h

X = [(2(3) + (5)) /(3 x ((3) + (5)))] x 2

X = [11 /(24)] x 2

X = 0.916 m
