Step-by-step explanation:

p = 2×(l+w)

=> l = 3w

p = 2×(3w+w)

320 = 2× 4w

320 = 8w

=> w = 320/8 = 40

l = 3×40 = 120

so,

The width = b. ) 40 ft

The length = d.) 120 ft

A recipe calls for 1/4

Tom [10]

So, if we break it down, this is just easy math! First we divide 16 tablespoons/4 and that gives us 4, then we multiply 1*3 and that equals 3! So 3*4 is equal to 12. So there are 12 teaspoons of broth in 1/4 cup of broth! Hope this helped! Brainliest is always appreciated.
