Step-by-step explanation:
bc dependng on 2lw+2lh+2hw, formula 8 and 10 would be length and width
Lets say
8=width
10=lenght
3in=height
u would do
2 x l x w + 2 x l h + 2 x h x w=
2 x 10 x 8 + 2 x 10 x 3 + 3 x 8=
160 + 60 + 48+=
268 is the sa

Answer:
maximum area will be 1058 square yards
maximum height will be 81 feet
Step-by-step explanation:
P = 2L +2W
but in this case it will be P= L+2W and P=92 yards
L+2W = 92
Solve for L , L = 92-2W
The area of rectangle A = L x W
Plug in L and simplify: A = (92-2W)W =92W -2W²
Plot in your calculator and look for maximum so when the width is 23 yards maximum area will be 1058 square yards.
Second problems is the maximum height of the rocket. Maximum will be at the vertex of the upside-down parabola.
