the area of trapizium is 400 cm distance between the parallel sides is 16 cm if one of the parallel sides is 20cm find the length of the other side
Answers
Answer:
Trapezium: It is a quadrilateral with two parallel opposite sides and two non-parallel sides.
Area of trapezium = 1/2 × l × (a + b)
Here, l = Distance between 2 parallel sides
a and b are the parallel sides
Given: Area of a trapezium = 400 cm², a = 20 cm and l = 16 cm
To find: Value of other parallel side (b) = ?
Solution: We know that area of a trapezium = 1/2 × l × (a + b)
Substituting the values,
400 = 1/2 × 16 × (20 + b)
400 ÷ 8 = 20 + b
50 - 20 = b
b = 30
∴ The length of other side = 30 cm
