Question

the area of a Trapezium is 720 cm square the ratio of parallel side is 2 ratio 1. if the distance between the parallel side is 20 cm find the length?

Answer 1

720= 1/2( 2a + a) × 20
3a = 72
a=24
so length of parallel sides 24cm & 48cm

Answer 2

Answer:

Step-by-step let the parallel sides be 2x and one x we can also say x.

720=1/2×(x+2x) ×20

720=1/2×3x×20

720=3x×10

3x=72

x=24
