The area of a trapezium is 475 cm2 and the height is 19 cm. Find the lengths of its two parallel sides if one side is 4 cm greater than the other
Question
Solution 1
Let's denote the shorter parallel side of the trapezium as 'a' (in cm). According to the problem, the longer parallel side is 'a + 4' cm.
The formula for the area (A) of a trapezium is given by:
A = 1/2 * (sum of the lengths of the parallel sides) * height
