A farmer needs to build a goat pen. The pen will be 6 yards wide and 14 yards long. The fencing material costs $4.00 per yard. How much will it cost to buy enough fencing material to build the goat pen?

it will cost $336 to buy enough fencing material to build the goat pen.

Step-by-step explanation:

The goat pen is rectangular.

The formula for determining the area of a rectangle is expressed as

Area = length × width

The pen will be 6 yards wide and 14 yards long. It means that the area of the pen is

6 × 14 = 84 yard²

The fencing material costs $4.00 per yard. Therefore, the amount that it will cost to buy enough fencing material to build the goat pen is

84 × 4 = $336

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
