The rectangular section, the length of which is 10 1/8 m and the width is 2/3 of the length, is surrounded by a 1.6 m high fence. Find the area of the fence.
First you need to find out the width of this section.
Since it is 2/3 of its length, we multiply the known width by the given part.
Will be:
10 1/8 * 2/3 = 81/8 * 2/3 = 27 * 2/8 = 54/8 = 6 3/4 meters.
Determine the perimeter of this site.
To do this, multiply the sum of the length and width of the site by 2 equal parts.
Will be:
2 * (10 1/8 + 6 3/4) = 2 * (10.125 + 6.75) = 2 * 16.875 = 33.75 meters.
To find out the area of the fence, we multiply the perimeter by the height.
33.75 * 1.6 = 54 m2
Answer: Fence area 54 m2
