Answer 1

Answer:

Given

Let length of parallel sides be 84cm and y cm

Area of trapezium= 1586 cm2

Let Height (h) =26 cm

We know that area of trapezium is × (sum of parallel sides) × height

Therefore Area of trapezium is × (84 +y) × 26 =1586 cm2.

× (84 +y) × 26 =1586

⇒(84 + y) × 13 =1586

⇒ 84 + y =

⇒ y =122— 84 = 38

... Length of the other parallel side is 38 cm.
