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

17. What is the area of the figure below?
Sidana [21]

If length of rectangle is 8 cm, breadth is 4 cm, side of square is 3 cm, base of triangle is 3 cm, then the area of figure will be 48.5 cm^{2}.

Given that length of rectangle is 8 cm, Breadth of rectangle is 4 cm,side of square is 3 cm,base of right angled triangle is 3 cm,height of triangle is 5 cm.

Area of figure=Area of rectangle+Area of square+Area of triangle

Area of rectangle=length*breadth

Area of square=Side*Side

Area of triangle=1/2 *Base*Height

Area of figure=8*4+3*3+1/2 *3*5

=32+9+1/2 *15

=41+15/2

=(82+15)/2

=97/2

=48.5 cm^{2}

Hence if length of rectangle is 8 cm, breadth is 4 cm, side of square is 3 cm, base of triangle is 3 cm, then the area of figure will be 48.5 cm^{2}.
