Answer:
Step-by-step explanation:
Perimeter = 84 cm
2*(length + width) = 84
2* (2x - 8 + x - 2) = 84
2*(2x + x - 8 - 2) = 84 {bring like terms together}
2*(3x - 10) = 84 {add/ subtract like terms}
Divide both sides by 2
3x - 10 = 42
3x - 10 +10 = 42 + 10 {add 10 to both sides}
3x = 52
Divide by 3,
x= 17 1/3
Length = 2x - 8
Answer:
$7.44
Step-by-step explanation:
$4.96/ 2= 2.48
$2.48 X 3 = 7.44
This is possible providing the garden is in the shape that has equal sides, such as a square or an equilateral triangle.
Area of a square is found by multiplying one side to the other, which would be the same as multiplying two same numbers.
