Formula for Area

Formula for Area

With Mr. Choudhury 

​If S= 3
So, A= S^2
A= 3^2
A= 9

Multiple Select

Area of Rectangle

• lw

• Base×Height

• wh

• Length + Base

Multiple Choice

Area of Triangle

• Base / Height x 2

• Base x Height

• Base x Height / 2

• Base/2

Multiple Select

Area of Square

• S/S

• S²

• S×S

• S₂

​If, a (Base)= 3
b (Base)=3.9
h (Height)= 4.5

• (3+3.9) = 6.9

• 6.9/2 = 3.45

• 3.45×4.5= 15.525 = 15.53

​We can Write like that also: Length × Height ÷ 2
