Problem: a courtyard is 21 meter long and 14 meter board is to be paved with bricks of dimensions 14 cm by 8 cm . the total number of bricks required is :
Rationale: "explanation : number of bricks = courtyard area / 1 brick area = ( 2100 ã — 1400 / 14 ã — 8 ) = 26250 option d"
annotated_formula: divide(multiply(multiply(21, const_100), multiply(14, const_100)), multiply(14, 8))
