Eylam wants to fence in his square backyard. He measures his backyard to be 875 square feet. Fencing is sold by the foot, how many feet of fencing will Eylam need?
*you can use a calculator
√875 = 29.6
Perimeter= sx4
= (29.6)(4)
= 118.32
Therefore, Eylam would need 118.32 of fence
Simplify: √64 x √9

What is √134
11.5 OR 11.6
Which is greater: 43 or 82
4x4x4 = 64
8x8=64
Therefore, they are equal
If 22 is 4, 23 is 8, and 25 is 32. What is a3 x a4 ?
22 = 4 AND 23 = 8
That means 22+23 = 25 = 32
Therefore, a3 + a4 = 3+4 = a7
If n2=49, solve for (n+1)2?
64
Which is smaller: √50 or 7?
