# In a trapezium-sh

Answer :

Given

Let length of first parallel side X

Length of other parallel side is 2X

Area of trapezium= 9450 m^{2}

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 cm^{2}.

× (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.
