28 - 45 = -17; the number subtracting is greater than the original number.
1760/40 = 44
He covered 44 ft^2 per lb.
2640/60 = 44
Again, he covered 44 ft^2 per lb.
In both cases, he covered 44 square feet per pound.
To cover 4480 sq ft, he needs:
4480/44 = 101.818181... = 101 9/11 pounds
The base of the square is 6 cm. 36(sqrt) is equal to 6. 6(6) = 36
<u>Answer</u>

<u>Explanation</u>
Area of a circle = πr²
Where r is the radius of the circle.
For a sector which is part of a circle, its area is given by;
Area of a sector = (Ф/360)πr²
where Ф is the angle making the sector at the center of the circle.
∴ Area of a sector = (Ф/360)πr²
= 60/360 × π × 3²
= 1/6 × π × 9
= 4.71 cm²
The green and the red are similar because the angel measurements are the same and the sides on the green triangle are 1/2 of the red triangle
