Answer:
3334650.54 euros
Step-by-step explanation:
We can calculate the area of the triangle knowing its sides by means of Heron's formula:
A = 
Where p is the semi-perimeter is equal to:
now, we replace:
p = 518.5
now, we replace this value and we are left with:
A = 
A = 50440.94 m^2
Now to know the price, we multiply by the price of the square meter:
50440.94 * 66.11 = 3334 650.54
In other words, the value of the parcel is 3334 650.54 euros
Applying the properties of a kite, m∠WZY = 128°.
<h3>Properties of a Kite</h3>
- The diagonals of a kite bisect each other perpendicularly.
- The main diagonal bisects the opposite angles.
Given:
m∠ZWY=41∘
m∠XYW=11∘
m∠WZY = (180 - 90 - 41) + (180 - 90 - 11)
m∠WZY = 49 + 79
m∠WZY = 128°
Therefore, applying the properties of a kite, m∠WZY = 128°.

Answer:
175 cm²
Step-by-step explanation:
Surface area of the square pyramid = area of the base + area of 4 triangles
So, in order to find the total surface area, first calculate the area of base then area of triangle
Area of the base can be calculated by s²
and s= 7cm
∴Area of the base = 7 x 7 = 49 cm²
As, Area of Δ = 1/2 b x h
Area of the 4 triangles = 4 x [ 1/2 x 7 x 9] (since there are 4 triangles)
Area of the 4 triangles = 4 x 31.5
Area of the 4 triangles = 126 cm²
Therefore, the surface area= Area of the base+ Area of the 4 triangles
Total Surface Area = 49 + 126 = 175 cm²
