From a rectangular plate with sides of 11 cm and 13 cm, a rectangle with sides of 6 cm and 3 cm was cut to find the area of the remaining part.
Look, your initial area is 11 * 13 = 143, then a rectangle was cut off from it, so you need to find the area of the second and subtract it from the original area, that is, the area of the cut figure is 6 * 3 = 18 and the remaining part after cutting is 143-18 = 125 cm.
