Answer:
width = 4.5 m
length = 14 m
Step-by-step explanation:
okay so first you right down that L = 5 + 2w
then as you know that Area = length * width so you replace the length with 5 + 2w
so it's A = (5 +2w) * w = 63
then 2 w^2 + 5w - 63 =0
so we solve for w which equals 4.5 after that you solve for length : 5+ 2*4.5 = 14
900 is the correct awnser
C) 10 feet
h² = 8² + 6² = 64 + 36 = 100
h = √100 = 10
Area of the base = 24 cm²
Height of the prism = 5 cm
Volume of the prism = 120 cm³
