Question

If the length of a rectangular garden is represented by (g + 1) and the width by (g + 2),

what expression would represent the area of the garden?

Answer 1

Area = length x width

Area = (g+1)(g+2) To multiply together, you would use FOIL

F = First

O = Outer

I = Inner

L = Last

F = (g)(g) = g²

O = (2)(g) = 2g

I = (1)(g) = g

L = (1)(2) = 2

Now add the terms together

g²+2g+g+2 Combine like terms

Area = g²+3g+2
