The area of a field in the shape of a trapezium measures 1440sq m. The perpendicular distance between its parallel sides is 24cm. If the ratio of the sides is 5:3, the length of the longer parallel side is:
Solution
Correct Answer: Option A
Area of field = \(\frac12\ast\left(5x+3x\right)\ast24\)= 96x sq.m
96x = 1440
=> x = \(\frac{1440}{96}\)
= 15
Hence, the length of longer parallel side = 5x = 75m
