Answer:B
Step-by-step explanation:
Using what is known as the "Triangle Inequality Theorem" a+b can not be less than c or else it is not a triangle. (A and B are the smallest sides of the triangle).
A) 6cm + 15cm = 21cm which is less than 23cm: Not a triangle
B) 5cm + 9cm = 14cm which is greater than 13cm: This makes a triangle and therefore the answer is B
C) 5cm + 8cm = 13cm which is less than 13cm: Not a triangle

Step-by-step explanation:
Answer: Wall 1 & 2 : 26 ft by 9 ft
Wall 3 : 18 ft by 9 ft
Area 1 : 26 ft x 9 ft = 234 ft²
Area 2 : 26 ft x 9 ft = 234 ft²
Area 3 : 18 ft x 9 ft = 162 ft²
Total Area : 234 ft² + 234 ft² + 162 ft² = 630 ft²
1 Gallon = 250 ft²
630 ft² ÷ 250 ft² per gallon = 2.52 gallons
