rectangle A has length 12 cm and width 6 cm and while rectangle B has llength 8 cm and width 5 cm .find the ratio of the size of and angle of A to the size of an angle of B
your question makes no sense to me.
all angles in rectangles are 90°, so what do you mean by the ratio of size of the angle?
Did you want the ratio of the areas?
