$|\Omega|=52\\ |A|=\underbrace{26}_{\text{red}}+\underbrace{4}_{\text{king}}-\underbrace{2}_{\text{red king}}=28\\\\ P(A)=\dfrac{28}{52}=\dfrac{7}{13}\approx54\%$

Corey has a garden in the shape of a square. The garden covers 64 square feet. What are the possible dimensions?

Valentin [98]

Answer:

64 = 1 x 64, 2 x 32, 4 x 16, or 8 x 8.

Step-by-step explanation:

If a garden covers 64 square feet total, then you simply find the common factors of 64.

64: 1, 2, 4, 8, 16, 32, 64.

So, the possible dimensions are,

64 = 1 x 64, 2 x 32, 4 x 16, or 8 x 8

Square feet total is 64. So put 4x16 or 8x8 or 2x32. Because if you multiply lets say 4x16, that would equal 64 square feet total.

If you were to multiply 64x64 that would be 4,096 square feet. and that would be a BIG NO NO!!!
