Answer:

57.97 cm²

Explanation:

Use the formula for area of a trapezoid


A = (a + b)/(2) h\\\\

where a and b are the two sides and h is the height

Here a = 7.8, b = 10.8, h = 6.2

Substituting we get

A = (7.9 + 10.8)/(2) * 6.2\\\\A = (7.9 + 10.8) * (6.2)/(2)\\\\\\7.9 + 10. 8 = 18.7\\\\(6.2)/(2) = 3.1\\\\\\A = 18.7 * 3.1 = 57.97\; cm^2
