Please help me find out what k is.
Ghella [55]

Answer: a) k=8

b) The area of the addition =30\text{ square feet}

The area of the entire patio after addition =80\ \text{square feet}

Step-by-step explanation:

Given: The area of the patio before addition = 50 square feet

The area of the addition portion is given by k^2-3k-10

We can see that dimension of the total portion is k\times(k+2)

therefore, the area of the patio with the addition portion = k\times(k+2)=k^2+2k

According to the question we have,

k^2-3k-10+50=k^2+2k\\\Rightarrow-3k+40=2k\\\Rightarrow\ 5k=40\\\Rightarrow\ k=8

Therefore,  The area of the addition =8^2-3(8)-10=64-24-10=30\text{ square feet}

The area of the entire patio after addition =  30+50=80\ \text{square feet}
