Answer:
90 square kilometers
Step-by-step explanation:
1. split the figure in small definite sections
2. find the areas of the smaller sections.
3. find the sum of the areas.
composite numbers less than 12={1,3,4,6,8,9,10}
To find the exact value using trigonometric identities
Exact form 456 divide a by 5
Decimal form 91.2
Mixed number form 91 1

First, you must understand the question. what % of 60 is 15, so I would write an equation to express this.
15 = 60x
From there, solve for x, so Divide by 60 on each side. The answer is 1/4, or 25%
9/12 so 12 triés because 9*3=27 so you then have to multiply 4*3*12
