Hope this helps
$7 \frac{1}{5} - 2 \frac{3}{5} = \frac{36}{5} - \frac{13}{5} = \frac{23}{5} = 4 \frac{3}{5}$

$8 \frac{2}{5} - 4 \frac{3}{5} = \frac{42}{5} - \frac{23}{5} = \frac{19}{5} = 3 \frac{4}{5}$
good luck

Look at Figure X diagrammed on the graph below. Which of the following statements are true

zzz [600]

Check the picture below.

so, if we slap the bottom surplus to the empty area on the top, we can pretty much close off those squares above, that gives a solid area of at least a 4x5 square, the red part and the yellow part there, and that'd give us a perimeter of 4+4+5+5 = 20 at least.

we might also be able to augment the left-right sides together to close off those squares as well, but even if we did, our area will just be about a 4x6 or 24 square units.

A) is the area larger than 14 square units? ✔

B) is the area less than 35 square units? ✔

C) is the perimeter more than 16? ✔
