Question

Open area of a house is in the shape of a trapezium with parallel sides in the ratio 3:5.Its area of 50 m² and the perpendicular distance between the parallel sides is 5m . Find the length of two parallel sides of the open area.

Answer 1

Let 2 parallel sides be 3x and 5x respectively
Atq,
Area = 1/2 ×h×(sum of parallel sides)

=) 50 m² = 1/2 x 5 x 8x
=) 8x= 50 ×2 /5
=) 8x= 20
=) x = 20/8 or 2whole 4/8 3x = 20/8×3 = 60/8 5x = 20/8×5= 100/8
