Answer:

area of a square A= a square

rectangle A= WL

triangle 1/2 bh

rhombus pq/2

paralogram a= bh

Verified answer

Answer:

Area of a:

1. Square = side×side
2. Rectangle = length×breadth
3. Triangle = 1/2×base×height OR 1/2×(area of parallelogram)
4. Rhombus = d1×d2/2
5. Parallelogram = base×height

Perimeter of a:

1. Square = 4×side
2. Rectangle = 2×(length+breadth)
3. Equilateral triangle = 3×side (Triangle = addition of all sides)
4. Rhombus = 4×side
5. Parallelogram = 2×(base+height)
