Question

write all the formulas from mensuration class 7th​

Answer 1

Mensuration — Class – 7

Perimeter of rectangle = 2 × ( L + B )

Perimeter of square = 4 × side

Perimeter of triangle = side + side + side

Breadth = p/2 + L

Length = p/2 + B

Area of rectangle = L × B

Area of square = side × side

Area of triangle = s/2 + s/2 + s/2

Circumference a circle = 2 π r ( π = 3.14 or 22/7 )

Diameter of a circle = d/2

Radius of a circle = r × 2

Area of a circle = π r²

Area of a parallelogram = base area × height

Area of aTrapezoid = 1/2 × b¹ + b²

Volume of cube = a³

Volume of cuboid = Length × Breadth × Height .
