Question

The area of a square photo frame is 250 cm square.Find the perimeter of the photo frame, leaving your answer correct to 1 decimal place.

Answer 1

Answer:

63.2

Step-by-step explanation:

Given that,

Area of square = 250cm square

a^2 = 250

a = √250

a = 5√10

We know that,

Perimeter of square = 4* side

Perimeter = 4 * 5√10

Perimeter = 20 * √10

Perimeter = 20 * 3.162

= 63.240

= 63.2 cm
