Answer:

40 inches

Explanation:

Try finding length first.

Area of square = 100 square inches

or, l square= 100 square inches[ using formula]

or, l=10 inches

Hence, length( l ) = 10 inches

Perimeter of square= 4l

= 4Ă—10 inches

= 40 inches

Answer:

40inches

Explanation:

If the area is 100 square inches, therefore on side of the area is just the square root of the area that is 10. Bcuz 10 x 10 =100 Square inch right? So one side is 10. A square has 4 sides, so multiply 10 by 4, u get 40inches
