Step-by-step explanation:
we know that the length of the parallel sides is 84cm and let us consider the other side as xcm Height (h) = 26cm Area of trapezium = 1586cm2 By using the formula Area of trapezium = ½ × (sum of parallel sides) × height 1586 = ½ × (84+x) × 26 1586 = ½ × (84+x) × 26 1586 = (84+x) × 13 84+x = 1586/13 84+x= 122 x = 122 – 84 = 38
∴ The length of the other parallel side is 38cm.
