area of trapezium with parallel sides a and b and the distance between two parallel sides as h
Answers
Answer:
The length of the parallel sides of a trapezium are in the rat: 3:2 and the distance between them is 10 cm. If the area of trapezium is 325 cm?, find the length of the parallel sides.
Solution:
Let the common ratio be x,
Then the two parallel sides are 3x, 2x
Distance between them = 10 cm Area of trapezium = 325 cm?
Area of trapezium = 1/2 (p, + P2) h
325 = 1/2 (3x + 2x) 10
325 = 5x x 5
- 325 = 25x
» X= 325/25
Therefore, 3x = 3 x 13 = 39 and 2x = 2 x
13 = 26
Answer:
A Trapezium is a quadrilateral with one pair of parallel sides. In cases, it is also defined as a plane figure with four sides, no of two which are parallel.
Formula®
Area of Trapezium = ½×(a + b)×h
where,
a, b = sides, h = height
Perimeter of Trapezium = a + b + c + d
where,
a, b, c, d = sides
A Trapezium is a four-sided polygon with two non-adjacent parallel sides or one set of parallel sides.
Examples:
Case 1: Find the area of a trapezium using the sides length as 4,5and the height 2..?
Step 1: Find the area.
Area = ½ * (a+ b) * h = ½ * (4 + 5) * 2 = ½ * 9 * 2 = 9.
Case 2: Find the perimeter of a trapezium using the sides length as 4,5,6,7
Step 1: Find the perimeter.
Perimeter = a + b + c + d = 4+5+6+7 = 22.
