Let W and L be width and length of the rectangular pen respectively.
Therefore,
Circumference, C = 2W+2L= 130 yd
Area, A = LW = 1050 yd^2=> L = 1050/W
Using the circumference expression and substituting for L;
130 = 2W + 2(1050/W) = 2W+2100/W
130*W = 2W*W + 2100
130W = 2W^2 +2100
2W^2-130W+2100 = 0
Solving for W;
W= [-(-130)+/- Sqrt ((-130)^2-4(2)(2100)]/2*2 = 32.5+/- 2.5
W = 30 or 35 yd
When W = 30, L = 1050/30 = 35
When W = 35, L = 1050/35 = 30
Therefore, W = 30 yd and L = 35 yd.
Answer:
GCF = 2 :)
Step-by-step explanation:
The greatest common factor is the biggest number that each number is divisible by.
There is no number greater than 2 that 14, 4 and 42 are all divisible by! :)
55% of 140 Percent
= 55/100 * 140/100 Divide 55 and 100 each by 5.
= 11/20 * 140/100 Cancel the zero at the top and bottom and divide 14 by 2.
= 11 * 7/100
= 77 Percent.
