Area of polygon = (number of sides × length of one side × apothem)/2
The length and width of a rectangular field fully enclosed with 218 metes fencing are 63 meters and 46 meters respectively.
The perimeter of a rectangle is the sum of the whole four sides. Therefore, the perimeter of a rectangle is defined as follows:
where
l = length
w = width
perimeter = 218 meters
The length of the field is 17 meters longer than the width, w. Therefore, the length is defined as follows:
The length and the width can be calculated as follows:
218 = 2(l + w)
218 = 2(17 + w + w)
218 = 34 + 4w
218 - 34 = 4w
184 = 4w
divide both sides by 4
w = 184 / 4
w = 46 meters
length = 17 + 46
length = 63 meters

Answer:
130°, 50°, 130°
Step-by-step explanation:
Two opposite angles of parallelogram are always congruent, so the measure of angle opposite to the angle 50° is 50° too.
Two consecutive angles of parallelogram always are supplementary (add up to 180°), so the angle consecutive to the angle 50° has the measure of
180° - 50° = 130°
Angle opposit to 130° angle has the measure of 130° too.
Answer:
Block 5
Step-by-step explanation:
The Shannon Diversity Index rewards larger numbers of species and more even distribution of species. On the face of it, Block 5, with its uniform distribution among 4 species, should have the highest index. When we do the calculation, we find this is the case. (see attachments)
