Let the short side be 3/5X and the other side be (3/5X+X)x2= 144, so that X=45 and 3/5 X =27 can be calculated.
Question 2. Rectangular carpet. The circumference is 4 14cm, and one side is twice as long as the other. Find the length of each side.
Let one side be x and the other side be 2. X (X+2X)x2=4 14。 Calculate that x is 69 cm and the other side is 2x6 9= 138cm.
