Answer:
The answer is 4.
Step-by-step explanation:
First you look in the parenthesis (PEMDAS)
Do the exponent first (PEMDAS).
You should end up with (16-8)/2
What you should do next is (8)/2 (PEMDAS)
Your last step leaves you with 4 (PEMDAS)
Four equivalent ratios:
1) 5:15
2)1:3
3) 10:30
4) 20:60
Half the perimeter is the length + the width
62/2 = 31
Area = length x width
16 + 15 = 31, 15 x 16 = 240
17 + 14 = 31, 17 x 14 = 238
20 + 11 = 31, 20 x 11 = 220
Answer: 20 meters x 11 meters
