Answer:
a. 15m
b. 7m
Step-by-step explanation:
- perimeter is the sides added up, there are four sides of a square, and all sides are equal
- equation s+s+s+s or s•4 (s=sides)
- so to find the length with the perimeter divide perimeter by 4
- 60/4=15
- the area of a square is s²
- so take the square root of the area
- √49=7
