Answer 1

Answer:

So it gives you a little picture and tells you what would the question be if you had this graph.

Step-by-step explanation:

The correct answer would be B, find the area because the 4x + 3 is your length and 3x is your length, A = length * width. So the answer is B, find the area.

Answer 2

Answer:

Step-by-step explanation:

A)  Length = 4x +3

Width = 3x

Perimeter = 2*(length + width )

    = 2*(4x + 3 + 3x)            {Add the like terms}

   = 2*(7x + 3)

    = 2*7x + 2*3

    = 14x + 6

B) Area = length * width

= (4x + 3) * 3x

= 4x *3x + 3*3x

= 12x² + 9x

C) x = 8

Perimeter =  14x + 6 = 14*8 + 6 =112 +6 = 118 units

Area = 12x² + 9x = 12*(8)² + 9*8  

       = 12*64 + 72

      = 768 + 72

      = 840 square units
