If the lengths of the two parallel sides of a trapezium are 7 cm and 9 cm and its area is 80 cm^{2} . Find the distance between its parallel sides (in cm).

Solution & Step-by-step Explanation

The formula for the area of a trapezium is: Area = \frac{1}{2} \times (a + b) \times h Where: a = 7 cm and b = 9 cm (lengths of the parallel sides) Area = 80 cm^{2} h = distance between parallel sides (height) Substitute the given values into the formula: 80 = \frac{1}{2} \times (7 + 9) \times h 80 = \frac{1}{2} \times 16 \times h 80 = 8 h h = \frac{80}{8} = 10 cm

Try it yourself before checking the explanation above.
