<h3>What is Geometrical figure?</h3>Geometric shapes are the mathematical figures that show how ordinary objects in our world are shaped. Shapes in geometry are the configurations of things with boundary lines, angles, and surfaces.
<h3>According to the given Information:</h3>Length of the rectangular patio is (x+25).
Width of the rectangular patio is (x+15).
Length of bench is 5.
Width of the bench is 1.
<h3>Area of rectangle:</h3>Area of a rectangle is:
A = Length x Width
Area of rectangular patio is:
A = (x + 25)(x + 15)
Area of bench is:
A = 10 x 3
= 30
The painting area is:
A = A - A
A = (x + 25)(x + 15) - 30
Therefore, the correct option is D.
