The expressions x2 - 14x + 49 and (x - 7)2 are equivalent.

(x + a)^2 = (x + a)(x + a) = x^2 + 2ax + a^2

In this case 2a = -14 so a= -7 and a^2 = 49

Considering the figures, the area that will be painted is of 38.9 square feet.

<h3>What is the area of a rectangle?</h3>


The area of a rectangle of length l and width w is given by:

A = lw

<h3>What is the area of a triangle?</h3>

The area of a triangle of base b and height h is given by:

A = \frac{bh}{2}

<h3>What is the area of a semi-circle?</h3>

The area of a semi-circle of radius r is given by:

A = 0.5\pi r^2

In this problem:

  • The rectangle with l = 6 ft and w = 8 ft will be painted, along with the triangle of dimensions b = 8 ft and h = 4 ft.
  • The semi-circle with r = 4 ft will not be painted.

Hence, the area that will be painted, in square feet, is given by:

A = 6 \times 8 + \frac{8(4)}{2} - 0.5\pi 4^2 = 64 - 8\pi = 38.9
