Question

The length of of a rectangle is 10mm and the width is 2.5mm, what is the area

Answer 1

The area for rectangle is (l x w) or (length times width) or (length x width) 

*just in case you get confused

so the length is 10, and the width is 2.5 so you plug in.

10 x 2.5 = 25

your answer is 25 mm²

hope this helps
