Yes you need the distance formula to find the Base and height.
Do you have a picture to go with this question ?
Step-by-step explanation:
83.10789742
round up and write
Area=legnth times width
192=(9+x)(13+x)
solve
expand
192=117+22x+x^2
minus 192 both sides
0=x^2+22x-75
factor
0=(x-3)(x+25)
set to zero
x-3=0
x=3
x+25=0
x=-25
not possible since that gives negative legnths and widhs
increased by 3
shorter is 9
9+3=12
C is ansre
Where x is the amount of cat food
50 - (19 3/4 + 18 7/8) = x
x = 50 - (19 6/8 + 18 7/8)
x = 50 - 38 5/8
x = 11 3/8
so, 11 and 3/8 pounds of cat food were donated to the shelter
