Answer:
38/3 = 12 2/3
Step-by-step explanation:
I believe it would be 115 plus 56. subtract that from 180. i believe thisbis your answer
Perimiter=2L+2W
w=x
P=80
80=2L+2x
diviide by 2
40=L+x
40-L=x
40-x=L
the area is found by legnth times width
LW or Lx
for a maximum area, try to get the legnths of the sides the same
therefor
L=W=x for max area
40=x+x
40=2x
divide 2
20=x
max area =legnth times width=20^2=400
note: all squares are rectangles, but not all rectangles are squares
L=40-x
A=(40-x)(x)
max area=400 cm^2
Answer:
(l-3)(l+10)
