Answer:

Area of the rectangle = 95 cm²

Explanation:

Perimeter of the rectangle = Sum of the measures of the sides of the rectangle

From the figure attached,

Perimeter of the rectangle = 2[(3x -1) + (2x + 3)]

39 = 2(5x + 2)

39 = 10x + 4

10x = 39 - 4

10x = 35

x = 3.5

Therefore, measure of the given sides will be,

Length = (3x - 1) cm

3x - 1 = (3×3.5) - 1

= 10.5 - 1

= 9.5 cm

Width = (2x + 3) cm

2x + 3 = (2×3.5) + 3

= 7 + 3

= 10 cm

Area of the rectangle = Length × width

= 9.5 × 10

= 95 cm²

Therefore, area of the rectangle is 95 cm².
