A swuare has an area of 108.16m2 work put the perimiter of the square​

41.6 m

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( s is the side length ), then

s² = 108.16 ( take the square root of both sides )

s = = 10.4

Then

perimeter = 4s = 4 × 10.4 = 41.6 m

im not sure

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
