Percentage - rhombus

If the rhombus side in the image increases by half, by what percentage will the area of the rhombus increase?

Correct answer:

p =  125 %

Step-by-step explanation:

b = a + a/2 = 1.5 a S1 = a2 sin α S2 = b2 sin α  S2 = (1.5a)2 sin α S2 = 1.52  a2 sin α = 1.52   S1  p = 100   S1S2S1 p = 100   S11.52   S1S1  p=100 11.521=125%
