multiplying decimals

If it is a square each side should be the same length. 3.8cm.

 

For finding area use the formula:

A=b(h)

Area=base(height)

 

3.8(3.8)=

14.44

If the length of one side length of a square is 3.8, then all the sidelengths are 3.8.

 

Let us use a formula to find the area:

 

\(A=s^2\)

\(A=3.8^2\)

\(A=3.8^2\Rightarrow 14.44\)

 

\(A=\boxed{14.44\space cm^2}\)

 

Hope that helps!
