Step-by-step explanation:
Area of square= side ×side
Let x meters be the length of a side of the square.
Perimeter= 4(side)
4x= 40
<em>Dividing by 4 throughout:</em>
x= 40 ÷4
x= 10
Area of garden
= x²
= 10²
= 100m²
Answer:
a = 3.5
Step-by-step explanation:
![\frac{a}{sin(A)} = \frac{c}{sin(C)} \\\\a = \frac{csin(A)}{sin( C )} \\\\a = \frac{3 sin(63^{o} )}{sin(49^{o} )} \\\\a = 3.5](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bsin%28A%29%7D%20%20%3D%20%5Cfrac%7Bc%7D%7Bsin%28C%29%7D%20%5C%5C%5C%5Ca%20%3D%20%5Cfrac%7Bcsin%28A%29%7D%7Bsin%28%20C%20%29%7D%20%5C%5C%5C%5Ca%20%3D%20%5Cfrac%7B3%20sin%2863%5E%7Bo%7D%20%29%7D%7Bsin%2849%5E%7Bo%7D%20%29%7D%20%5C%5C%5C%5Ca%20%3D%203.5)
Answer:
He determined pounds per dollar by dividing 10 by 25 but wrote the unit rate as a dollar value.
Step-by-step explanation:
Given
![\frac{10\ pounds}{\$25} = \frac{10\ pounds}{25} / \frac{\$25}{25} = \frac{0.4}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B10%5C%20pounds%7D%7B%5C%2425%7D%20%3D%20%5Cfrac%7B10%5C%20pounds%7D%7B25%7D%20%2F%20%5Cfrac%7B%5C%2425%7D%7B25%7D%20%3D%20%5Cfrac%7B0.4%7D%7B1%7D)
![Unit\ Price = 40\ cents](https://tex.z-dn.net/?f=Unit%5C%20Price%20%3D%2040%5C%20cents)
![40\ cents * 6 = \$2.40](https://tex.z-dn.net/?f=40%5C%20cents%20%2A%206%20%3D%20%5C%242.40)

Determine Ming's error
Ming's error is from here
![\frac{10\ pounds}{\$25} = \frac{10\ pounds}{25} / \frac{\$25}{25} = \frac{0.4}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B10%5C%20pounds%7D%7B%5C%2425%7D%20%3D%20%5Cfrac%7B10%5C%20pounds%7D%7B25%7D%20%2F%20%5Cfrac%7B%5C%2425%7D%7B25%7D%20%3D%20%5Cfrac%7B0.4%7D%7B1%7D)
He calculated the unit rate as pound per dollar.
So, after calculating the unit rate, the unit should be:
![Unit\ Rate = 0.4\ pound/\$](https://tex.z-dn.net/?f=Unit%5C%20Rate%20%3D%200.4%5C%20pound%2F%5C%24)
But instead, he solved as:
![Unit\ Rate = \$0.4/ pound](https://tex.z-dn.net/?f=Unit%5C%20Rate%20%3D%20%5C%240.4%2F%20pound)
<em>Hence, (a) is correct</em>
