In a trapezium-sh
Answer :
Given
Let length of first parallel side X
Length of other parallel side is 2X
Area of trapezium= 9450 m2
Let Height (h) =84 m
We know that area of trapezium is × (sum of parallel sides) × height
Therefore Area of trapezium is × (X + 2X) × 84 =9450 cm2.
× (X + 2X) × 84 =9450
⇒ (3X) × 42 =9450
⇒ 126X = 9450
⇒ 2X + 6 = = 75
⇒X = 17
... Length of the parallel sides is X=75 m and 2X = 150 m.
Therefore length of the longest is 150 m.
