I'm not 100% sure what this all means because I'm in a different school but, I believe they have a side length of 4600.
P.S. If it doesn't work, I am so sorry
Total 27inch^
Calculation of 1 rectangle +1 triangle(11-7=4 is the base)
triangle x^+4^=5^
x^+16=25
x^=9
x=3 (height=3)
Sides of triangle Base=4 Hypotenuse=5 height =3
area 1/2 4 x 3 =2x3=6
Area triangle =6
Area Rectanglel 7x3=21
21+6=27 inch^ total area
The answer would be a -3/4 I’m almost positive
