Answer:
40
Step-by-step explanation:
To find the perimeter, first we need to find the side lengths.
If 100 cm is the area then we need to find what number squared is 100
10 x 10 = 100
So 10 is the side length. P= s + s + s +s
10 + 10 + 10 +10 = 40
Answer:
x = - 5
Step-by-step explanation:
Given
= 2x ( multiply both sides by 3 to clear the fraction )
2x - 20 = 6x ( subtract 2x from both sides )
- 20 = 4x ( divide both sides by 4 )
- 5 = x , that is x = - 5
