first take the base as 4 cm long and place the needle of the compass on the left, point and make a 90 degree angle, now open the compass 9 cm long and by placing the needle on the right point of the base cut an arc on the 90 degree angle. Join all the points and label the figue. I have also attached a picture which will help you.
