a room of 6 m 20 cm long and 5 m 74 cm broad is to be paved with square tiles . find the least number of square tiles required to cover the floor .
"explanation : area of the room = 620 * 574 sq cm size of largest square tile = h . c . f of 620 cm and 574 cm = 2 cm area of 1 tile = 2 * 2 sq cm no . of tiles required = ( 620 * 574 ) / ( 2 * 2 ) = 88970 answer : c ) 88970"
divide(multiply(add(multiply(6, const_100), 20), add(multiply(5, const_100), 74)), power(divide(add(multiply(6, const_100), 20), power(const_2, const_4)), const_2))
