The dimensions of a triangular lot are 100 feet by 50 feet by 75 feet. If the price of such land is $3 per square foot, how much does the lot cost?
Does this question have anything to do with volume?
Area of Triangle when the length of the three sides is known:
where P is total perimeter and a, b and c are the lengths of the three sides.
A similar formula is:
where P is half the perimeter, or
Once you find the area, multiply it by $3 to get total cost of lot.
