QUESTION:-
The area of a trapezium is 225 cm² and its height is 0.15 m. If one of the parallel sides. parallel sides is longer than the other by 6 cm, find the length of the two parallel sides
ANSWER :-
the length of two parallel sides are 12 cm and 18 cm
STEP BY STEP SOLUTION :-
let one of the parallel sides be x cm
Then , the other parallel side = (x + 6) cm
Area of trapezium = ½ × height × sum of parallel sides
➙ 225 cm² = ½ × 0.15 m × ( x + x + 6 ) cm
➙ 225 cm² = ½ × 15 cm × (2x + 6) cm
➙ 225 = ½ × 15 × (2x + 6)
➙ 225 × 2 = 15 × (2x + 6)
➙ 2x + 6 = 225 × 2 / 15
➙ 2x + 6 = 30
➙ 2x = 30 - 6
➙ 2x = 24
➙ x = 24/2
➙ x = 12
➙ x + 6 = 12 + 6 = 18
