Question

3.
The longer side of a trapezium is 10 cm and the distance between its parallel sides is 8 cm. If its area
is 50 cm”, what is the length of the smaller parallel side ?
(a) 10 cm
(b) 2 cm
(c) 2.5 cm
(d) 3.5 cm​

Answer 1

Step-by-step explanation:

option (c) is the right answer

area of trapezium = 1/2(sum of its parallel side)× height

50= 1/2 (10 + small parrallel side ) × 8

100= (10 + small parallel side)×8

12.5 = 10 +small parallel side

small parallel side = 2.5

Answer 2

Answer:

c 2.5 cm

Step-by-step explanation:

given,

let other parallel side be b

Area of trapezium = 1/2×(sum of parallel side)×h

50 cm² = 1/2 × (10+b) × 8

50 = (10+b) × 4

12.5 = 10 + b

b = 2.5 Ans.
