Answer:
I have no clue as to what the options were, but the answer is 61 and three-fifths.
Step-by-step explanation:
<em>Well, the fraction options were a little distorted, so I'll work it out anyway.</em>
<em />
7 • 8 4/5
7(8 + 4/5)
<em>7 • 8 is 56, and 7 • 4/5 is 28/5.</em>
56 + 28/5
<em>28/5 as a mixed-number fraction (I think that's what it's called) is 5 3/5.</em>
56 + 5 + 3/5
61 + 3/5
61 3/5 (61 and three-fifths)
There!
<em>(Sorry about not getting the options...)</em>
A= 320 cm2 and that is the answer
