Question

All formulas of perimeter and area

Answer 1

Explanation:

perimeter of rectangle=2(l+b)

perimeter of square=4 x Side

perimeter of triangle=a+b+c

perimeter of circle=2pi r (or) pi d

area of square=S x S

area of rectangle=l x b

area of triangle=1/2 x b x h

area of parallelogram=b x h

area of rhombus=1/2 x diagnol1 x

=diagnol2

area of circle=pi r square

Answer 2

Answer: Perimeters and areas of square rectangle and triangle are given below..

Explanation: Perimeter of square=4×side and area=(side)^2. Perimeter of rectangle=2×(l+b) and area= l×b. Perimeter of triangle= sum of its three sides. Semi-perimeter= sum of three sides divided by 2. Area of triangle by heron's formula= √S(S-a)(S-b)(S-c)... Hope these all formulae helps you....
