Answer:
eight people drink 6 glasses of water
Step-by-step explanation:
750 sq ft
Step-by-step explanation:
since the fencing is going around the perimeter, you have to have two sides with the width of 25 feet, you would use 50 feet of fencing for 2 of the sides. You will have 60 feet of fencing left, divided by 2 (length of the garden) = 30 feet long.
The area (length x width) or (25 x 30) = 750 sq ft of garden space. Draw a rectangle with 25 ft on two parallel sides and 30 ft on the other two sides and show these equation= 25 x 2= 50, 110 - 50 = 60
60 ÷ 2 = 30, 30 x 25 = 750
