Question

The parallel sides of a trapezium measure 12 cm and 20 cm. Calculate its area if the

distance between the parallel lines is 15 cm, the area of the trapezium is​

Answer 1

Answer:

___________________________

Given-

Parallel lines in a trapezium

Sides of trapezium i.e., 12cm,20cm

___________________________

To Find-

area of trapezium

___________________________

Solution-

Area of trapezium = ½ × perpendicular distance between parallel sides × sum of parallel sides

= ½ × 15 × (12+20)

= 1/2 × 15 × 32

= 15 × 16

= 240 cm²

___________________________

Answer 2

Answer:

Area of trapezium=1/2 × ( sum of parallel sides ) × height

1/2×(12+20)×15

1/2×32×15

16×15=240 cm²
