Answer:
Step-by-step explanation:
Area of Square = 3 × area of rectangle
length of rectangle = 5²+ 5 = 30
length is thrice its width it means width = 10
area of rectangle = length × breadth = 30 × 10 = 300cm²
area of square = 3 × area of rectangle = 3 × 300 = 900cm²
area of square = (side )²
side = √area of square = √900 = 30cm
perimeter of square = 4 × square = 4×30 = 120cm
