Question

the area of a trapezium is 224 square and its height is 14 cm if one of the parallel side is longer than other by 8 cm find the length of two parallel sides​

Answer 1

Answer:

24

Step-by-step explanation:

the area of trapezium = 1/2 ×(8 + 8 + 2x) × 14

so

1/2 × (8 + 8 + 2x) × 14 = 224

or, 16 + 2x = 224/14 × 2

or, 2x = 32 - 16

or, x = 16/2

or, x = 8

so the first parallel side = 8

and the second parallel side = 2×8 + 8 = 24
