Question

If a rectangle has a perimeter of 26 cm and both length and width are whole numbers what is the biggest possible area?

Answer 1

Step-by-step explanation:

2(l+b)= 26cm

l+b= 13cm

To get the biggest possible area we must try to split the number into two equal parts ( give or take)

here we can choose l= 7cm and b= 6cm

Thus area = 7cm×6cm= 42cm²
