Question

a field is in the shape of a Trapezium one of its parallel side is twice the other parallel side and distance between them is 100mif area of a field is 10500m2 find the length of parallel side

Answer 1

Let the parallel sides be a and 2a

Height = 100 m

Now,

Area = 1/2 ( a +2a) × h

=> 10500 = 1/2 (3a) × 100

=> 105000 × 2 / 100 = 3a

=> 210 = 3a

=> a = 70

Parallel sides are 70 m and 140 m

Answer 2

Let the parallel sides be a and 2a

Height = 100 m

Now,

Area = 1/2 ( a +2a) × h

=> 10500 = 1/2 (3a) × 100

=> 105000 × 2 / 100 = 3a

=> 210 = 3a

=> a = 70

Parallel sides are 70 m and 140 m
