The are of his backyard is 10.4 times 15.83 or 164.632 yd^2 the sod piecs are 1.33 by 1.33 or 1.78 yd^2 so divide 164.632 by 1.78 or 164.632/1.78=92.5 pieces of sod if he is buying the sod in pieces, he will have to buy 93 pieces because he can't buy 1/2 sod
The answer is 3 and you get that by using the formula for the area of rectangle, p=2L+2W 44=2(4+5w) + 2w 44=8+10w + 2w 44=8+12w 44-8=8+12w-8 36=12w 36/12=12w/12 3=w If you plug 3 back into the original formula then you see that it is equal to the perimeter of 44 P=2(4+5w) + 2w P=2(4+5•3) + 2(3) P=2(19) +6 P=38+6 P=44
