Question

The parallel sides of a trapezium are 20 cm and 15 cm and the distance between them is 12 cm. Find its area?

Answer 1

Answer:

hi

area = 1/2 x 20 + 15 x  12

=1/2 x 35 x 12

a = 210 is the area

Answer 2

Answer:

Let the common ration be x,

Then the two parallel sides are 3x, 2x

Distance between them = 10 cm

Area of trapezium = 325 cm²

Area of trapezium = 1/2 (p₁ + p₂) h

325 = 1/2 (3x + 2x) 10

⇒ 325 = 5x × 5

⇒ 325 = 25x

⇒ x = 325/25

Therefore, 3x = 3 × 13 = 39 and 2x = 2 × 13 = 26

Therefore, the length of parallel sides area are 26 cm and 39 cm.
