Solved Examples
Question 1: Find the centroid of trapezoid with the given dimensions; a = 12′ ; b = 5′ ; h = 5′
Solution: Given,
a = 12′; b = 5′; h = 5′
Using centroid of trapezoid formula,
x = $\frac{b + 2a}{3(a + b)}$ × h
x = $\frac{5 + 2 \times 12}{3(12 + 5)}$ × 5
x = 2.84
Hence, the centroid of the trapezoid is at a distance of 2.84′.

Microsporogenesis comprises the events which lead to the formation of the haploid unicellular microspores. During microsporogenesis the diploid sporogenous cells differentiate as microsporocytes (pollen mother cells or meiocytes) which divide by meiosis to form four haploid microspores.
