Question

Answer part a and b please and explain thx

Answer 1

Part A: the area of a rectangle is A= lw, so

A= lw

Height= 6x+3.= 9x

Width= 8

Which makes the expression to this area 9x x 8 ( 9x times 8 )

Part B: you do the same to get the expression here, so the expression would be

6x x 12 ( 6x times 12 )

The answer to this part is yes because both end up being 72x once you get the answer of each.
