Question

the area of traepezium is 720cm². the ratio of the parallel side is 2:1. if the distance between the parallel side is 20cm . find the length of the parallel side ​

Answer 1

Answer:

24 cm and 48 cm

Step-by-step explanation:

∵ Sides are in the ratio of 2:1,

Let the sides be x and 2x

Area of trapezium = 1/2 (sum of parallel sides) × distance between them

720 = 1/2 (x+2x) × 20

720 = 1/2 × 20 × 3x

720 = 10 × 3x

720/10 = 3x

72 = 3x

72/3 = x

24 = x

∴ Sides are 24 cm and

2x = 2×24 = 48 cm
