The systems of equations that could be used to solve the problem is
5n = 3d
5n = 3d3d + 5n = 4
Given:
numerator = n
denominator = d
Ratio = 3 : 5
Equation 1
n / d = 3/5
cross product
n × 5 = d × 3
5n = 3d
Equation 2
(n + 2) / (d + 2) = 3/5
cross product
(n + 2) 5 = (d + 2)3
5n + 10 = 3d + 6
collect like terms
10 - 6 = 3d - 5n
4 = 3d - 5n
3d + 5n = 4
Therefore, the systems of equations that could be used to solve the problem is
5n = 3d
5n = 3d3d + 5n = 4

Answer:
66.24 (This answer does not match to any of the options...)
Step-by-step explanation:
This shape can be divided into 2 different shapes. A triangle and a rectangle.
Area of a Triangle = 
× base × height
= × 8.8 × 7.8
= 34.32
Area of a Rectangle = Length × Width
= (19.2 - 7.8) × (8.8 - (3+3))
= 11.4 × 2.8
= 31.92
Total area = 34.32 + 31.92 = 66.24
