Question

write a some formula which is related to chapter name mensuration​

Answer 1

Answer:

• Area of the Area = 1/2 x base x height

• If a , b , c are the sides of the traingle ,

then perimeter of the triangle = a + b+ c

• Semi – perimeter= a+b+c/2
• Area of the triangle = √s(s−a)(s−b)(s−c)
• Area of the equilateral triangle = 3√4a2

• The perimeter of rectangle = 2(l + b).
• Area of rectangle = l × b; (l and b are the length and breadth of rectangle)
• Diagonal of rectangle =√ l2+b2b2

• Perimeter of square = 4 × S.
• Area of square = S × S.
• Diagonal of square = S√2; (S is the side of square)

• Perimeter of parallelogram = 2 (sum of adjacent sides)
• Area of parallelogram = base × height

• Area of rhombus = base × height
• Area of rhombus = 12× length of one diagonal × length of other diagonal
• Perimeter of rhombus = 4 × side

• Circumference of circle = 2πr = πd ,Where, π = 3.14 or π = 22/7
• r is the radius of circle
• d is the diameter of circle
• Area of circle = πr2
• Area of ring = Area of outer circle - Area of inner circle.
