Answer:
answer is 8
Step-by-step explanation:
area of rectangle = l × b
area of square = a²
it is said in the question that, area of square should be equal to area of rectangle.
so, both the areas should be equated.
area of rectangle = area of square
l × b = a²
16 × 4 = a²
64 = a²
a = √64
a = 8cm
therefore, length of each side of square will be 8cm
