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

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
