Answer:
≥
Step-by-step explanation:
1 1\4x2 1\5 = 2 3/4
5/6 x 2 1/5 = 1 5/6
w + 4
------------------------
l l
l l w
l l
------------------------
Perimeter would be the sum of all the sides so: (w+4) + w + (w+4) + w
Perimeter is 60 yards according to your problem so: (w+4) + w + (w+4) + w = 60 yds
1.Simplify/combine like terms:
w + 4 + w + w + 4 + w =
4w + 8 =
Now it's a 2-step algebra equation
4w + 8 = 60
2.Subtract 8 on both sides
4w = 56
3.Divide both sides by 4
w = 14
45 = 3x3x5
Or you could simplify it to 3^2x5
Since you keep proportional dimensions, the proportion between the old and new dimensions must be the same. So, if we call the new height
, the preservation of the width/height ratio is written as
![4 \div 6 = 9 \div h](https://tex.z-dn.net/?f=%204%20%5Cdiv%206%20%3D%209%20%5Cdiv%20h%20)
Solving the proportion for
yields
![h = \frac{6\cdot 9}{4} =\frac{3\cdot 9}{2} = \frac{27}{2} = 13.5](https://tex.z-dn.net/?f=%20h%20%3D%20%5Cfrac%7B6%5Ccdot%209%7D%7B4%7D%20%3D%5Cfrac%7B3%5Ccdot%209%7D%7B2%7D%20%3D%20%5Cfrac%7B27%7D%7B2%7D%20%3D%2013.5%20)
7.6375 =
1 Decimal Place = 7.6
<span>2 Decimal Place = 7.64
</span><span>3 Decimal Place = 7.638
</span><span>4 Decimal Place = 7.6375
</span>
So the answer is 7.64 .
The 3 rounds up because 7 is bigger than 5...
