Answer 2

Answer:

Question:-

ldentify the different geometrical shapes in howrah bridge. Write its perimeter and area formula?

Answer:-

The different geometrical shapes in howrah bridge are

Square, triangle, equilateral triangle,rectangle,parallelogram,rhombus,trapezium etc.

Area and perimeter of geometrical shapes:-

Square:-

Area=a^2

Perimeter=4a (a=one side)

Triangle:-

Area:-1/2×base× height

Perimeter:-a+b+c

Equilateral triangle:-

Area:-√3/4 a^2

Parallelogram:-3a

Rectangle:-

Area:-length×breadth

Perimeter:-2(l+b)

Parallelogram:-

Area:-Base×height

Perimeter:-2(a+b)

Rhombus:-

Area:-1/2×diagonal1×diagonal2

Perimeter:-4a

Trapezium:-

Area:-1/2×h×(a+b)

Perimeter:-a+b+c+d
