(A)3.44 square feet

Step-by-step 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 =

Area of 1 circle

Area of the 4 circles

Therefore:

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