Answer:
5.4ft²
Explanation:
Area of yellow region
= area of square - area of circle
Area of square= side ×side
Area of circle= πr²
5ft is the length of a side of the square, as well as the diameter of the circle.
Diameter= 2 ×radius
Radius or circle, r
= 5 ÷2
= 2.5 ft
Area of yellow region
= (5 ×5) - π(2.5²)
= 25 -6.25π
= 5.4 ft² (to nearest tenth)
