What formula is used to find out the Perimeter of a square?
p = 4s
s = one side of the square
What formula is used to find out the Area of a Square?
If l is the side-length of a square, the area of the square is l2 or l × l.
What is the area of a square having side-length 3.4?
The area is the square of the side-length, which is 3.4 × 3.4 = 11.56.

What formula is used to find out the Diagonal of a square?
d = s(square root of 2)
s = one side of the square
A square has two diagonals, which are line segments linking opposite vertices (corners) of the square.
What formula is used to find out the Perimeter of a rectangle?
p = 2l + 2w
where l = length and w = the width of the rectangle
What formula is used to find out the Area of a rectangle?
a = lw
The area of a rectangle is the product of its width and length.
What is the area of a rectangle having a length of 6 and a width of 2.2?
The area is the product of these two side-lengths, which is 6 × 2.2 = 13.2.
What formula is used to find out the Diagonal of a rectangle?
d = (square root(l to the second power + w to the second power))
What formula is used to find out the Perimeter of a triangle?
The perimeter, P, of a triangle is given by the formula P = a + b + c where a, b and c are the side lengths of the triangle.
What formula is used to find out the Area of a Triangle?
Consider a triangle with base length b and height h.
The area of the triangle is 1/2 × b × h.
What is the area of the triangle having a base of length 5.2 and a height of 4.2?
The area of a triangle is half the product of its base and height, which is 1/2 ×5.2 × 4.2 = 2.6 × 4.2 = 10.92.
What formula is used to find out the Radius of a circle?
r = 1/2(d)
Where d = the diameter of the circle
What formula is used to find out the diameter of a circle?
d = 2r
What formula is used to find out the Circumference of a circle?
c = 2(Pi)r
What formula is used to find out the Area of a circle?
a = Pi(r squared)
What formula is used to find out the Volume of a cube?
v = s cubed
where s = the length of one side of the cube
What formula is used to find out the Volume of a Rectangular box?
v = lwh, where l = the length, w = the width, and h = the height of the box
What formula is used to find out the Volume of a cylinder?
v = (Pi)(r to the second power)(h)
where r = the radius of the cylinder and h = the height of the cylinder
What formula is used to find out the Surface area of a cube?
SA = 6(s to the second power)
What formula is used to find out the Surface area of a rectangular box?
SA = 2lw + 2wh + 2lh
What is the Distance formula?
d = rt
where d = distance. r = rate, and t = time
What is the Interest formula?
i = prt
i = interest, p = principal, r = rate, and t = time
