First, determine the area of the triangle. When all sides of the triangle are given, you can determine its area through the semi-perimeter. This is the half of a perimeter.

s = (30 + 25 + 40)/2

s = 47.5

Then, we apply the Heron's formula:

A = square root [s(s-a)(s-b)(s-c)], where a, b and c are side lengths of the triangle

A = square root [47.5(47.5-30)(47.5-25)(47.5-40)]

A = 374.53 sq feet

To find the number of cows, divide the area by 50:

Number of cows = 373.53 ft2 / 50 ft2 per cow

Number of cows = 7.4906

The estimated number of cow is 7.

**Answer:**

174

**Step-by-step explanation:**

mark brainliest

D=sqrt((7-5)^2+(-4-3)^2)

d=sqrt(2^2+(-7)^2)

d=sqrt(4+49)

d=sqrt(53)

**d=7.28 units**

W=35 is the answer

One of the characteristics of legal English is **archaic English words.**

Usually, in legal texts you would use words that aren't normally used in everyday speech, in order to show the importance and formality of that document.
