48. A square's sides are equal, so we know that its area is a number multiplied by itself, or squared. To find the length of one side, you must take the square root of its area, 156.25, which is 12.5. To find the square's perimeter (how much fence we need to go around the garden) you must multiply that side by 4, to get 50. Antonine has 40 ft already, so he only needs 10 more ft, and each ft costs 4.97. Our final answer is 10*4.97, or $49.70.
49. The square root of 12 is about 3.46, plus 2 is our answer, about 5.46 cm.
You have to move both decimals over and then divide. So the answer is 25.
0.05, 0.5, 5/8
5/8 is greater than 0.5 since 0.5 = 1/2 which equals 4/8
