The dimensions of a triangular lot are 142 feet by 67 feet by 141 feet. if the price of such land is $3 per square foot, how much does the lot cost?

First we have to find the area. We multiply all the sides and divide it by 2 since triangles are half of squares. Then we get 670,737. Then we multiply that by 3 which then we get  $2,012,211. I hope this helps!

The answer would be c
