Aclassroom is 24 metres long and 21 metres wide. find the area of the classroom

The formula for the area of a rectangle is:

Length × Width

OR

L ×  W

In this case...

L = 24 m

W = 21

^^^Plug these numbers into the formula for the area of a rectangle

24 ×  21

504

The area of this class room is 504

Hope this helped!

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
