Question

What is the formula of quadrilaterals ???!???​

Answer 1

Answer:

Area of a rectangle = Length × Breadth or L × B

Area of a rectangle = Length × Breadth or L × BPerimeter of rectangle = 2 × (L + B)

Area of the square = a × a = a²

Area of the square = a × a = a²Perimeter of the square = 2 × (a + a) = 4a

Perimeter of parallelogram= 2 × (l + b)

Perimeter of parallelogram= 2 × (l + b)Area of the parallelogram = l × h

If the side of a rhombus is a then, perimeter of a rhombus = 4a

If the side of a rhombus is a then, perimeter of a rhombus = 4aIf the length of two diagonals of the rhombus is d1 and d2 then the area of a rhombus = ½ × d1 × d2

Perimeter of the trapezium= Sum of lengths of all the sides = AB + BC + CD + DA

Perimeter of the trapezium= Sum of lengths of all the sides = AB + BC + CD + DAArea of the trapezium = ½ × (Sum of lengths of parallel sides) × h = ½ × (AB + CD) × h

Perimeter of the trapezium= Sum of lengths of all the sides = AB + BC + CD + DA

Perimeter of the trapezium= Sum of lengths of all the sides = AB + BC + CD + DA

Area of the trapezium = ½ × (Sum of lengths of parallel sides) × h = ½ × (AB + CD) × h
