The problem is: A rectangular shaped field, 567 feet by 963 feet, is to be fertilized before planting a new crop. If the fertilizer costs $31 a bag and can cover 1525 square feet, how many bags will be needed and what will they cost?
My question is do I find the area or the perimeter first, and then solve?
the perimeter: P=2l+2w
2(567)+2(963)
1134+1926
3060
then I setup the problem to find the cost as:
31x + 1525 = 3060
31x=1535
x=49.5
problem to find how many bags as:
31+1525x=3060
1525x=3029
x=1.9
