Answer 1

Step-by-step explanation:

Given The area of a square poster is 987 cm(square). Find the perimeter of the poster leaving your answer correct to 1 decimal place

• Given area of a square poster a = 987 sq cm
• We need to find the perimeter of the poster.
• Now we have Area of a square = a^2 (side x side)
•                                   987 = a^2
•                          So a^2 = 987
•                         Or a = 31.41 cm
•   Now we have perimeter = 4 x side
•                                            = 4 x 31.41
•                                           = 125.6
•   Therefore perimeter of the poster will be 125.6 units
