Answer:
Step-by-step explanation:
She pays 19.2 for 2.4 walnuts
Price of 1 walnut = 19.92÷2.4 = 8.3
Do 5*12 because that's 5*(4+4+4) which the 4s are the base lengths added together. So you have 60 for one part of the figure.
Next, you have 2*4 left to add on to the figure which is 8.
So 60+8=68 is your answer
68 units^2
