A triangular shaped sign board and a parallelogram shaped notice board have the same base and same area. If the sides of the triangle are 35 \(cm\), 40 \(cm\) and 45 \(cm\), and the parallelogram stands on the base 40 \(cm\), find the height of the parallelogram shaped notice board. (Use \(\sqrt{5} = 2.24\))
