Answer:

(A)3.44 square feet

Explanation:

Length of The Square = 4 feet

Area of the Square poster board = 4 X 4=16 Square Feet

In each of the circles,

Diameter = 2 Feet

Radius = 2/2 = 1 Feet

Area of a circle =
$\pi r^2$

Area of 1 circle
$=\pi*1^2=\pi ft^2$

Area of the 4 circles
$=4*\pi=4\pi ft^2$

Therefore:

Area of the leftover Poster= Area of the Square- Area of the 4 Circles

$=16-4\pi\\=16-4*3.14\\=16-12.56\\=3.44 ft^2$
