A square has a side of 8cm. The area of the square increases by 50%. Work out the percentage increase in the length of the side. Please explain fully how u do it
because the side has to be increased by 50% you find half of 8, which is 4 and you add 8+4 because you add the increased amount 8+4=12 you then just find the area.... so 12x12= 144
