The dimensions of a courtyard were measured with a meter stick and hence its area was
found to be 400 sq m. Later on it was detected that the length of the meter stick actually
measures 90 cm and not one metre. Find the correct area of the courtyard

Answer:

400 x 90 = 36000 sq. cm will be the area, 1 m = 100 cm, hence the corrected area will be 360 square meters
