<u>The square root of 198 is between 14 and 15.</u>
Step-by-step explanation:
Let's calculate the square root of 198, this way:
√198 = 14.07
<u>The square root of 198 is between 14 and 15.</u>
We know that
2l + 2w = 24
And:
l = 3w
By substitution:
2(3w) +2w = 24
6w + 2w = 24
8w = 24
w = 3 metres
l = 3 x 3 = 9 metres
Total cost = 24 x $25 = $600
