Answer: 56 inches
Step-by-step explanation:
Given that:
Area of square frame = 196 in²
Area of a square = a²
Where a = side length
Hence side length (a) of the square :
a² = 196
a = √196
a = 14
To find the length of the ribbon required :
Find the perimeter of the square :
Perimeter of a square = 4a
= 4 * 14
= 56 inches
Answer:
it's 8-3m
x = 5
Add the equations
x + y = 3
x - y = 7
––––––––
2x = 10
Divide both sides by2
Note: for the equations in the question,
none of the given answers are correct.
