y is 2 radical 3
Answer:
158.76 cm²
Step-by-step explanation:
Quadrilateral ABCD is composed of 2 right triangles
Construct the line BD, then
Δ ABD and Δ BCD are the 2 right triangles.
The area (A) of a triangle is calculated using
A =
bh ( b is the base and h the perpendicular height )
Δ ABD with b = 18 and h = 7.5
A =
× 18 × 7.5 = 9 × 7.5 = 67.5 cm²
Δ BCD with b = 15.6 and h = 11.7
A =
× 15.6 × 11.7 = 7.8 × 11.7 = 91.26 cm²
Thus
area of ABCD = 67.5 + 91.26 = 158.76 cm²
To find the density of racon all you have to do is to divide number of racoons with surface area because as name says you need to get x number of racoons per m^2
its own name tells you what you need to divide with what.
answer is:
20/10 = 2 raccoons per m^2
