area of big square = 1764m²
S² = 1764
S = √1764
S = 42m²
area of small square = 784m²
s² = 784
s = √784
s = 28m²
area left = 1764-784 = 980m²
the area left out is divided into 5 parts
so,
area of each part = 980/5 = 196m²
side of each small part = √196 = 14m
so,
perimeter of each part = 4×14 = 56m
S² = 1764
S = √1764
S = 42m²
area of small square = 784m²
s² = 784
s = √784
s = 28m²
area left = 1764-784 = 980m²
the area left out is divided into 5 parts
