Answer:
The area of the nonagon is 270cm²
Step-by-step explanation:
The area of a regular polygon is given by

where 'a' is the apothem and 'p' is the perimeter.
The apothem is a=6cm.
The perimeter is p=9×10=90cm.
We substitute the apothem and the perimeter to get:


Answer:
A = 36 in.²
Step-by-step explanation:
The area of a parallelogram can be determined by the formula:
A = bh
The base length is 12 inches and the height is 3 inches.
A = 12in. * 3in.
A = 36 in.²
9600 kilobytes...
30 x 32000 divided by 100 = 9600

Answer:
FG = 9.7ft
Step-by-step explanation:
Find the diagram in the attachment.
The diagram is a right angled triangle since one of its angle is 90°
Using SOH CAH TOA to calculate the length FG which is the hypotenuse.
According to SOH
Sin∠G = Opposite/Hypotenuse
To get the ∠G,
∠F+∠H+∠G = 180°
18°+90°+∠G = 180°
∠G = 180°-108°
∠G = 72°
Sin72° = 9.2/FG
FG = 9.2/sin72°
FG = 9.67feet
FG = 9.7ft (to the nearest tenth of a foot)
