The area of trapezium is 262.5sq cm and the perpendicular distance between its parallel sides is 15cm. What is the sum of parallel sides?
Answers
Answer:
Step-by-step explanation:
Height = 15 cm
Area = 262.5 cm^2
=> 1/2 (sun of parallel sides) × Height = 262.5
=> ( sum of parallel sides) × 15 = 525
=> sum of parallel sides = 525 / 15
=> sum of parallel sides = 35 cm

Step-by-step explanation:
Area of trapezium, A = (a+b)*h/2 where a and b are the lengths of the parallel sides and h the distance between them. Here we are given A = 262.5 sq cm and h = 15 cm, therefore (a+b)/2 = 262.5/15 = 17.5. Hence the sum of the parallel sides, a+b = 2*17.5 or 35 cm.
Area of trapezium, A = (a+b)*h/2 where a and b are the lengths of the parallel sides and h the distance between them. Here we are given A = 262.5 sq cm and h = 15 cm, therefore (a+b)/2 = 262.5/15 = 17.5. Hence the sum of the parallel sides, a+b = 2*17.5 or 35 cm.Check: A = 35*15/2 = 262.5 sq cm.
