Answer:
The perimeter of the rectangle is expressed as; 
Step-by-step explanation:
Given;
area of the rectangle, A = 36 cm²
width of the rectangle, = W
Let L represent the length of the rectangle,
A = L x W
The perimeter of the rectangle is calculated as;
P = 2(L + W)
Substitute the value of L into the above equation;
Thus, the perimeter of the rectangle is expressed as
Answer:
x (children) = 58
y (students) = 66
z (adults) = 29
Step-by-step explanation:
Step 1: Write system of equations
x + y + z = 153
5x + 7y + 12z = 1100
1/2x = z
The best way to solve the systems of equations is to use an augmented matrix:
Top row: [1 1 1 | 153]
Middle row: [5 7 12 | 1100]
Bottom row: [1/2 0 -1 | 0]
And then put it in RREF form:
Top row: [1 0 0 | 58]
Middle row: [0 1 0 | 66]
Bottom row: [0 0 1 | 29]
