1.	find the perimeter of the rectangle whose length and breadth are as give in the following table length 12 cm and breadth 19 mm
Answer» -Length of the rectangle = 12 cmBreadth of the rectangle = 19 mmTo Find :-The PERIMETER of the rectangle.Analysis :-Firstly, convert the length to millimeters.Then substitute the values in the formula of perimeter of a rectangle and find the perimeter accordingly.Solution :-We KNOW that,l = Lengthb = Breadthp = PerimeterBy the formula,Given that,Length (l) = 12 CM = 120 mmBreadth (B) = 19 mmSubstituting their values,Perimeter = 2(120 + 19)= 2(139)= 278 mmTherefore, the perimeter of the rectangle is 278 mm.
