if their base is the same, the exponents must also be the same for the equation to be true.
Answer:
The area of rug is 48.9 m^2
Step-by-step explanation:
Let's assume radius of rug is r m
we know formula for circumference as

we are given
C=24.8
and then we can solve for r


now, we can use area formula

we can plug r
and we get


So,
The area of rug is 48.9 m^2
Answer: 17.14 ft
<u>Step-by-step explanation:</u>
The area of the flower bed is 60 ft x 80 ft = 4800 ft²
The perimeter of the sidewalk that surrounds the flower bed is:
- 2(60 ft) + 2(80 ft)
- = 120 ft + 160 ft
- = 280 ft
The area of the sidewalk is:
area of sidewalk = area of flower bed
280w = 4800


≈ 17.14

There are 10 feet of posts on each side. That means there are 40 feet of fencing in total. If you divide that by two (to represent posts being 2 feet apart) then you get 20. There are 20 posts needed.
