Answer
28 ounces = 793.79 grams
28 ounces = 0.79 kilograms.
Step by step explanation
1 ounce = 28.3495 grams
Now let's convert 28 into grams.
Here we have to multiply 28 by 28.3495
28 x 28.3495 = 793.787 grams
Now let's convert 793.787 into kilograms
1 kilograms = 1000 grams
793.787 grams = 0.79 kilograms
Perimeter = 18 miles
Perimeter = 2a + 2b
2a + 2b = 18
a = ?
b = 7
18 = 2a + 2*7
18 = 2a + 14
2a = 18 - 14
2a = 4
a = 2
Area = a * b
Area = 2 * 7 = 14 miles2
