Answer:
52m
Step-by-step explanation:
Area of the square floor = 169 m²
For a square with each side 's' , area will be s². Similarly , for a square with area 'a' , length of each side will be √a. So,
Length of each side of floor = √169 = 13m
For a square with each side 's' , its perimeter will be 4s. Hence ,
Perimeter of the kitchen = 13 × 4 = 52m
Answer:
52 ft
Step-by-step explanation:
area of a square is l x w. all sides are equal so the l = w
A = 169 ft^2 so each side is the square root of 169 which is 13 ft
perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal
Perimeter = 13ft × 4 = 52 ft

Step-by-step explanation:
340 = 215 + 25x
DO INVERSE OPERATIONS ~ MINUS BOTH SIDES OF THE = SIGN
340 - 215 = 125
215 - 215 = 0
125 = 25x
DIVIDE BOTH SIDE NOW
125 / 25 = 5
25x / 25 = 1 = x
