Question

 I need help in my math q

Answer 1

It usually means the dimensions of a rectangle:

              6 inches

-------------------------

|                              |

|                              | 4 inches

|                              |

|                              |

-------------------------

 

The area of a rectangle is its length times its width, posed as the following formula:

A = lw

Thus we have:

A = 6 in * 4 in

6 * 4 = 24

in  * in = in²

So the area of this rectangle is 24 inches².
