The Number of inches in the perimeter of a square is 3 more than the # of square inches in its area.Find the.?

Question

Length of a side

step by step pleaze

length of the side,

seriously need help

the sum of the square of 2 consecutive odd positive intergers is 130.

Answer 1

ok. the perimeter of a square is 4 * s
the area of the square is s^2
(s = length of side)

so, the if the inches in the perimeter is 3 more than the square inches in it's area

4s= s^2 + 3

now subtract 4s

s^2 -4s + 3 = 0

factor

(s - 3) (s - 1) = 0

s-1=0 or s-3=0

s=1 or s= 3

Answer 2

assumption : x is the side length of that square,

so :

perimeter is 4x
area is x^2

perimeter of a square is 3 more than the # of square inches in its area
it means:
4x = x^2 + 3
0 = x^2 - 4x + 3
factorize :
0 = (x-3) (x-1)

first solution :
x-3 = 0
x = 3

second solution :
x-1 = 0
x = 1

so the length of sides could be 1 inch or 3 inches.

Answer 3

let S=LENGTH OF A SIDE

PERIMETER=4*S
AREA=S*S

4*S=S*S+3

REGROUPING:
S*S-4*S+3=0

SOLVE FOR S USING QUADRATIC FORMULA:
S=1 OR S=3.

CHECK IT! IT WORKS!
