Answer 1

Answer:

Given:-

Area of trapezium shaped field is 600m².

Height of trapezium is 24 m.

Length of one of its parallel side is 20 m.

To Find:-

Length of the other parallel side.

Solution:-

Here, Area of Trapezium = \dfrac{1}{2}\times height \times ( sum\ of \ parallel \ sides)21×height×(sum of parallel sides)

Let the another parallel side be x m.

So, Putting values we get,

⇒ 600 m² =  \dfrac{1}{2}\times 24 \ m \times ( 20 \ m + x \ m )21×24 m×(20 m+x m)

⇒ \dfrac{600 \ m^{2} \times 2}{24 \ m} = ( 20 \ m + x \ m )24 m600 m2×2=(20 m+x m)

⇒ 50 \ m - 20 \ m = x50 m−20 m=x

⇒ x = 30 \ mx=30 m

Hence, Other parallel side of trapezium is 30 m.
