It is in the hundreds place. The number would be said as one thousand five hundred seventy six
The cities are 14.7 inches apart on the map.
An inch on the map is 10 miles on the ground. That is what a scale of 1 in : 10 miles means.
If a distance is 147 miles on the ground therefore, on the map it will be:
= Distance on map / conversion factor
= 147 / 10
= 14.7 inches
The distance between the two cities on the map is 14.7 inches.

To solve this problem you must apply the proccedure shown below:
1. You have that the formula for calculate the area of a triangle is:
A=bh/2
Where A is the area of the triangle, b is the base of the triangle and h is the height of the triangle.
bh/2=124
bh=124x2
bh=248
2. The problem asks for the new area of the triangle <span>if its base was half as long and its height was three times as long. Then, you have:
Base=b/2
Height=3h
3. Therefore, when you substitute this into the formula for calculate the area of a triangle, you obtain:
A'=bh/2
(A' is the new area)
A'=(b/2)(3)/2
A'=3bh/4
4. When you substitute bh=248 into </span>A'=3bh/4, you obtain:
<span>
A'=186 units</span>²
<span>
The answer is: </span>186 units²
