Mensuration & Geometry
No matter how grown up you are, you have to always remember some basics. Mensuration is the topic which you must have dealt in matriculation & this is all out about geometric shapes. So just refresh following formulas & get ready to score high.
Formulas to remember
Area of rectangle (A) = length(l) * Breath(b)
Perimeter of a rectangle (P) = 2 * (Length(l) + Breath(b))
Area of a square (A) = Length (l) * Length (l)
Perimeter of a square (P) = 4 * Length (l)
Area of a parallelogram(A) = Length(l) * Height(h)
Perimeter of a parallelogram (P) = 2 * (length(l) + Breadth(b))
Area of a triangle (A) = (Base(b) * Height(b)) / 2
