Use the given length of a different side of the triangle to determine the value of x if x is the length of one side. Every side of an equilateral triangle is the same. Multiply the length of one side of the triangle by three to find the value of x, if x is the triangle's perimeter.
Answer:
21 gallons
Step-by-step explanation:
We can solve this problem by ratios
126 miles 378 miles
-------------- = -------------
7 gallons x gallons
Using cross products
126 *x = 378 *7
126x =2646
Divide each side by 126
126x/126 = 2646/126
x =21
