Answer:
15 inches
Step-by-step explanation:
Suppose length of original square is L inches.
Now, to form a new square the length increases by 2.5 inches
So, new length=L+2.5 inches
Given that, perimeter of new square =70 inches.
Formula:-
Perimeter=4*length of square
Therefore 70=4*(L+2.5)
70 =4 L+10
4 L=60
L=15 inches
Answer:
The original length of each side was 15 inches.
Step-by-step explanation:
In this case we have to have clear that the perimeter of square consists in the addition of the length of each one of its four sides, this is:
The new square has a perimeter of 70, and we have to find the original length of each side, the equation will be:
We have to clear a:
The original length of each side was 15 inches.
