<u>Area of a Rectangle</u>
Given L as the length of a rectangle and W as its width, the area is calculated as:
A = L.W
Bob's swimming pool has L = w + 14 and a width of W = w + 8. Additionally, there is a walkway around the pool 4 feet wide. This walkway adds 2*4=8 to each dimension, thus: L = w + 22, W = w + 16.
Calculating the area:
A = (w + 22)(w + 16)

Answer:
(2, - 1 )
Step-by-step explanation:
3x - y = 7 → (1)
2x + 3y -= 1 → (2)
multiplying ( 1) by 3 and adding to (2) will eliminate y
9x - 3y = 21 → (30
add (2) and (3) to eliminate y
11x = 22 (divide both sides by 2 )
x = 2
substitute x = 2 into either of the 2 equations and solve for y
substituting into (2)
2(2) + 3y = 1
4 + 3y = 1 (subtract 4 from both sides )
3y = - 3 ( divide both sides by 3 )
y = - 1
solution = (2, - 1 )
