Answer:

Step-by-step explanation:
Width=(Length-2) units
W=(L-2) units
Area of the rectangle= 35 square units
Area = length* Width

Subtracting 35 both sides:

Solving the quadratic equation for 'L' ;
Using factorization:

Taking common from the equation :

OR

The length cannot be negative, therefore Length(L)= 7

Correct me if I am incorrect
Sqrt(49)*sqrt (-1) -4 = 7i-4
Answer:
B. 
Step-by-step explanation:
<em><u>To find the perimeter, use the formula:</u></em>
P = a + b + c
P = 12 + 12 + 9.7
P = 33.7
<em><u>To find area, use the formula:</u></em>
A = 
A = 
A = 
A = 54
