Step-by-step explanation:
(2*5)*4 = 10*4 = 40
2*(5*4) = 2*20 = 40
Length (L): L
width (w): (2/3)L
Perimeter (P) = 2L + 2w
290 = 2(L) + 2(2/3)(L)
870 = 6L + 4L
870 = 10L
87 = L
width (w): (2/3)L = (2/3)(87) = 2(29) = 58
Answer: width = 58 ft, length = 87 ft
<span>Sum of Interior Angles = (Number of Sides -2) • 180 degrees
</span>
<span>Number of Sides = [Sum of Interior Angles / 180 degrees] +2
</span><span>Number of Sides = (5,400 / 180) +2
</span><span>Number of Sides = 32

Answer:
306 gallons
Step-by-step explanation:
Caroline traveled 544 miles on 16 gallons. We do some simple math and divide 544/16 and receive 34 miles/gallon. All we do now is multiply 34 * 9 and we receive 306 gallons.
