Independent work on the topic “The area of a trapezoid”

Option 1

1. The bases of a trapezoid are 5 cm and 9 cm, its height is 6 cm. What is the area of the trapezoid?
2. In an isosceles trapezoid, the bases are 6 cm and 10 cm and the angle at the base is 450. What is the area of the trapezoid equal?
3. In a rectangular trapezoid, the bases are 5 cm and 9 cm and the smaller side is 4 cm. What is the area of the trapezoid?
4. In an isosceles trapezoid, the height from the apex of an obtuse angle divides the larger base into two segments, the larger of which is 26 cm. Find the area of the trapezoid if its height is 10 cm.
5. The bases and height of a trapezoid are related as 5:6:4. Find the greater base of the trapezoid if its area is 88 cm2.
