Evaluation of the expression using order of operation gives 26/11.
How to evaluate the expression
Given 13 ÷(2.5-1-3).33 = 13 ÷ 33( 2 x 5 - 1 - 3)
To evaluate this expression we need to apply the order of operation rule, BODMAS or PEMDAS.
13 ÷(2.5-1-3).33 = 13 ÷ 33( 2 x 5 - 1 - 3) Evaluate multiplication
= 13 ÷ 33(10 - 1 - 3) Evaluate what is in the bracket
= 13 ÷ 33(6) Evaluate division
= 13/33 x 6
= 78/ 33 = 26/11
Therefore, evaluating the expression gives 26/11.

Step-by-step explanation:
Solving the following system of equations:
Let
Putting value of x^2 in eq(2)
Now, finding value of x
Putting y=-5
y=-5, x= 2i and y=-5 , x= -2i
Since we need to find x and y coordinates and its value cannot be in terms of i so we will not consider these as answer
Putting y=3
So,

Perimeter
2l + 2w = 27
l + w = 13.5
Area
l*w = 35
(35 / l) + l = 13.5
35 + l^2 = 13.5l
l^2 - 13.5l + 35 = 0
Using this equation, we can find the length first
then width can be found
