Find the area of trapezium whose parallel sides are 20 cm and 18 cm l...
To find the area of a trapezium, we can use the formula:
Area = 1/2 × (a + b) × h
Where:
a and b are the lengths of the parallel sides of the trapezium
h is the distance between the parallel sides
Given:
Length of one parallel side (a) = 20 cm
Length of the other parallel side (b) = 18 cm
Distance between the parallel sides (h) = 15 cm
Let's plug in the values in the formula to calculate the area.
Area = 1/2 × (20 + 18) × 15
= 1/2 × 38 × 15
= 19 × 15
= 285 cm²
Therefore, the area of the trapezium is 285 cm².
So, the correct answer is option C) 285 cm².
