Answer:
<em>20,845 square meters</em>
<em />
Step-by-step explanation:
We can use the formula for area of a triangle to figure this out easily.
Area = 
Where
a and b are the two side lengths of the triangle given, and
C is the ANGLE BETWEEN the two sides
<em>Clearly, we see that one side is 218.5 and other is 224.5 and the angle between them is given by 58.2 degrees. Now we simply substitute these values into the formula and get the area:</em>
<em>
</em>
<em />
<em>Rounding, we get the area to be 20,845 square meters</em>
Lateral area = 2(16 x 4) + 2(8 x 4) = 2(64) + 2(32) = 128 + 64 = 192 m^2
Id say d is best way to go
Answer:
x = 8
Step-by-step explanation:
The triangle is isosceles with legs congruent, both x
Using Pythagoras identity in the right triangle
x² + x² = 16²
2x² = 256 ( divide both sides by 2 )
x² = 128 ( take the square root of both sides )
x =
=
=
×
= 8
