Answer:
=12
12step by step explanation:
=solution:
solution: area of gym= 144
solution: area of gym= 144we know that,
solution: area of gym= 144we know that, area of square= L²
solution: area of gym= 144we know that, area of square= L² or,144= L²
solution: area of gym= 144we know that, area of square= L² or,144= L² or, (12)² = L²(12² means 12×12=144)
solution: area of gym= 144we know that, area of square= L² or,144= L² or, (12)² = L²(12² means 12×12=144) or, 12= L
solution: area of gym= 144we know that, area of square= L² or,144= L² or, (12)² = L²(12² means 12×12=144) or, 12= L therefore, L = 12
