Answer:
81
Step-by-step explanation:
Since ,
Wire of Length 36 cm is bent to form a square so,
perimeter of the square = Length of the wire
Hence, perimeter of the square = 36cm
Therefore, one side of the square = 36 cm ÷ 4
= 9 cm
So area of the square = side × side = 9 cm × 9cm
Answer: They would be intersecting lines
Step-by-step explanation:

A polygon is any figure sided with three sides and above such that triangle (3) is the smallest polygon. A nonagon is a polygon with 9 sides. To get the sum of interior angles of a polygon we use the formula;
(n-2) 180 or (n-4)90 where n is the number of sides.
Therefore, for a nonagon the sum of interior angles = (9-2) 180 = 1260 degrees
If we add all the angles we should get 1260, considering the remaining angles to be each x
Thus 138+154 +145 +132 +128 +147 +130 + x +x =1260
= 974 + 2x = 1260
= 2x = 286
= 143
therefore, each of the other angles was 143
If the mower is pulled over a flat horizontal surface, then first get the component of the force in the direction of the mower's displacement:
(120 N) cos(30°) = 60 √3 N ≈ 103.923 N
Then the work done by the boy on the mower over a distance of 12.8 m is
(103.923 N) (12.8 m) ≈ 1330.2 Nm ≈ 1330 J
