Answer:
a=50
Step-by-step explanation:
a + 2a + 30 = 180
3a + 30 = 180
(-150 from both sides)
3a = 150
(Divide by 3 from both sides)
a = 50
216/200=%
1.08 which equals 108%
Area of a square = L * L
As you know 17 * 17 = 289
So length of one side of square equals 17
When multiplying by 100 just add 2 zero's behind your second number. ANSWER:5,000
