Question

The area of a trapezium is 0.05 m² and its height is 20 cm. If one of the parallel sides is shorter than
the other by 8 cm, find the length of the longer parallel side.​

Answer 1

Step-by-step explanation:

Area of Trapezium => 0.05

1/2 x sum of parallel sides x height => 0.05

1/ 2 x y - 8 x y x 20 = 0.05

1/2 x 2y - 8 = 0.05

y => 0.05 + 4 /2

y = 2.05cm

longer side=> 2.05cm
