To find out the area of a given rectangular trapezoid, we will use the formula: S = h * (a + b) / 2, where h is the smaller side edge, height (h = 8 cm); a – the first smaller base (a = 5 cm); b – the second larger base (b = 13 cm).
Let’s perform the calculation: S = h * (a + b) / 2 = 8 * (5 + 13) / 2 = 72 cm2.
Answer: The area of a given rectangular trapezoid is 72 cm2.
