Find the sum of the lengths of the bases of a trapezium whose area is 4.2 m2 and whose height is 280 cm. |
|
Answer» Area of trapezium = \(\frac{1}{2}\)(sum of lengths of parallel sides) x altitude Area of trapezium = \(\frac{1}{2}\)(sum of sides) x altitude Sum of parallel sides = \(\frac{2\times area}{2.8}\) = \(\frac{2\times 4.2}{2.8}\) = 3 Therefore sum of length of parallel sides = 3 m |
