✔ 最佳答案
Length of side = 1 cm sayArea = L x L
Area = 1 x 1 cm²
Area = 1 cm²

Formula:
= (perimeter/4)²
= (4/4)²
= 1²
= 1
Answer: 1 square unit of measure
Proof:
Find the sides:
= 4/4
= 1
Compute the area
= 1 * 1
= 1
= (perimeter/4)²
= (4/4)²
= 1²
= 1
Answer: 1 square unit of measure
Proof:
Find the sides:
= 4/4
= 1
Compute the area
= 1 * 1
= 1

(4 ÷ 4)^2
= 1^2
= 1 x 1
= 1
= 1^2
= 1 x 1
= 1

OK, so the perimeter is 4
That means each side has length 1
And the area is 1*1 = 1 unit
That means each side has length 1
And the area is 1*1 = 1 unit

okay look the perimeter is four so therefore each side is 1 so to find the area u have to times two sides right so it would be one ..

if the perimeter s 4 (4a) then the value of a=1 and so the area(a*a) = 1m2.

x+x+x+x=4 =>4x=4=>x=1
area= x*x=1*1=1
area= x*x=1*1=1

A square has 4 sides that are equal. perimeter is the total length of all sides and to figure out the area use length*width,
