7.5 x 9.0 feet in metric, first work out 7.5 x 9.0 feet which is 67.5 square feet, now convert 67.5 square feet to metric which is 6.2709552 square metres.
Assuming the playground is a perfect rectangle, the perimeter of the playground will be 330 meters.
3 x 5 x 5 = 75 2 x 3 x 3 x 5 = 90
75 x 0.20 = 15 15 + 75 = 90 90 is 20% greater than 75. Alternate way of solving the problem: 75 x 1.20 = 90
7.5 feet is 90 inches @12 inches per foot.
75 x 80 = 6,000
75% of 90= 75% * 90= 0.75 * 90= 67.5
90 x 7 = 630 sq ft
gcf(75, 45, 90) = 15 Using prime factorization: 75 = 3 x 5² 45 = 3² x 5 90 = 2 x 3² x 5 hcf = 3 x 5 = 15
12,375 square feet (165 x 75 = 12,375)
75 cubic feet
90 feet x 262 feet equates to about 1/2 acre (0.541322314 acres).
5/6 x 90 is 75.
