Option 3) 6 cm.
The formula for the area of a trapezoid is A = (1/2)(b1 + b2)h, where b1 and b2 are the lengths of the bases and h is the height. We are given A = 21 cm2, b1 = 3 cm, and b2 = 4 cm. Plugging these values into the formula, we get:
21 = (1/2)(3 + 4)h
21 = (1/2)(7)h
21 = 3.5h
h = 21/3.5
h = 6
Therefore, the height of the trapezoid is 6 cm.

The area of a trapezoid is given by the formula:
A = (1/2)(b1 + b2)h
where b1 and b2 are the lengths of the bases, and h is the height. Plugging in the given values, we get:
A = (1/2)(4 + 6)(7)
A = (1/2)(10)(7)
A = 35
Therefore, the area of the trapezoid is 35 square inches.
