SELECT THE CORRECT ANSWER IN EACH OF THE FOLLOWING:
1. The parallel sides of a trapezium measure 14cm and 18cm and the distance between them is 9 cm. The area of the trapezium is
Solution: We know that the given details are:
Length of the parallel sides are 14cm and 18cm
Height (h) = 9cm
By using the formula,
Area of trapezium = ½ × (sum of parallel sides) × height
= ½ × (14+18) × 9
2. The lengths of the parallel sides of a trapezium are 19cm and 13cm and the area is 128cm2. The distance between the parallel sides is
Solution: we know that the length of the parallel sides is 19cm and 13cm
Let us consider Height (h) = x cm
Area of trapezium = 128cm2
By using the formula Area of trapezium = ½ × (sum of parallel sides) × height
128 = ½ × (19+13) × x
128 = ½ × 32 × x
128 = 16x
x = 128/16
∴ The distance between the parallel lines is 8cm.
