Question

what is the formula of area and square root and perimeter ​

Answer 1

Answer:

l×b

2(l+b)

I hope you understand

Answer 2

Answer:

Area of Rectangle Area = l × w l = length w = width

Area of Square Area = a2 a = sides of the square

Area of a Triangle Area = 1/2 b×h b = base

h = height

Area of a Circle Area = πr2 r = radius of the circle

Area of a Trapezoid Area = 1/2 (a + b)h a =base 1

b = base 2

h = vertical height

Area of Ellipse Area = πab a = radius of the major axis

b = radius of the minor axis

Perimeter Formulas for different geometrical figures:

Geometric Shape Perimeter Formula Metrics

Parallelogram 2(Base + Height)

Triangle a + b + c a, b and c being the side lengths

Rectangle 2(Length + Width)

Square 4a a =Length of a side

Trapezoid a +b+c+d a, b, c, d being the sides of the trapezoid

Kite 2a + 2b a = Length of the first pair of equal sides

b = Length of the second pair of equal sides

Rhombus 4 x a a = Length of a side
