Answer
First part
Perimeter = 100 cm
Second part
Area = 576 cm²
Step-by-step explanation
To solve this, we need to know that the area and perimeter of a square of length L is given as
Area = L²
Perimeter = 4L
For the first part
Area = 625 cm²
L = ?
Area = L²
625 = L²
Take the square root of both sides
√625 = √L²
25 = L
L = 25 cm
Perimeter = 4L = 4 (25) = 100 cm
For the second part,
Perimeter = 96 cm
L = ?
Perimeter = 4L
96 = 4L
Divide both sides by 4
(96/4) = (4L/4)
24 = L
L = 24 cm
Area = L² = 24² = 576 cm²
Hope this Helps!!!
