Explanation Formula used: Area of the trapezoidal field, A = 1 2 ( l 1 + l 2 ) h . Calculation: To draw a diagram by using the given data which is shown in fig 1. Compute the base length of trapezoidal. As AE is parallel to BD and AB is parallel to ED . Hence, A B = E D = x and B D = A E = y . CE is calculated by using Pythagoras Theorem, A C 2 = C E 2 + A E 2 ( 2 y ) 2 = C E 2 + y 2 C E 2 = 4 y 2 − y 2 C E = y 3 Hence, base length of trapezoidal is E D + C E = x + y 3 . Perimeter of the trapezoidal is 1500 m. Hence, A B + B C + C D + D A = 1500 . On further simplification, 1500 = A B + B C + C D + D A 1500 = x + y + 2 y + x + y 3 2 x = 1500 − ( 3 y + y 3 ) x = 1500 − ( 3 y + y 3 ) 2 Now, Substitute x = 1500 − ( 3 y + y 3 ) 2 in area of trapezoid A = 1 2 ( l 1 + l 2 ) h . Here, l 1 = x , l 2 = x + y 3 and h = y . Area of trapezoid becomes, A = 1 2 ( l 1 + l 2 ) h = 1 2 ( x + x + y 3 ) y = 1 2 ( 2 x + y 3 ) y = 1 2 ( 2 ( 1500 − ( 3 y + y 3 ) <
