3 feet width is added to both sides .
so the dimensions become 34 feet and 36feet
hence the fencing length required or the perimeter= 2(l+b)
= 2( 34+36)
= 2(70)
= 140feet fence
Answer:
Step-by-step explanation:
<u>Area of circle:</u>
<u>Circumference of circle:</u>
<u>Given</u>
<u>Find r using the second formula:</u>
- 2πr = 55
- 2*3.14r = 55
- r = 55/6.28
- r = 8.8 (rounded)
<u>Find area using the first formula:</u>
- A = 3.14*8.8²
- A = 243 m² (rounded)
The answer is 77 becuase you have to add all of the sides that are same as the number
3 times x equals to 646
3x=646
