Answer:
Width = 5.52meters
Length = 27.52meters
Attachment explain in details
We know that
Area of a regular polygon = (1/2)*apothem<span>*perimeter
</span>perimeter <span>of the regular decagon=10*a
where
a is the length side of the decagon
in this problem
a=1.8 ft
so
</span>perimeter of the regular decagon=10*1.8----> 18 ft
Area of a regular decagon = (1/2)*2.8*18----> 25.2 ft²
<span>Round to the nearest whole number------> 25 ft</span>²
the answer is
25 ft²
You could make circle like apples until you get all of them I hope this is right
Answer:
72cm^2
Step-by-step explanation:
Think of the whole figure as 3 rectangles. Your first one has an area of 8cm*3cm=24cm^2, your second one has an area of (12cm-3cm-3cm)*(8cm-4cm)=6cm*4cm=24cm^2, and your third one has an area of 8cm*3cm=24cm^2. Adding all of the areas together, we have 24cm^2+24cm^2+24cm^2=72cm^2 as the total area of the figure.
