Answer:
8.333333334 cm
Step-by-step explanation:
area of square =100 cm^2
area of rectangule = 12b
12b=100
b= 25/3 cm
Answer:
8
Step-by-step explanation:
side of square = 10cm
perimeter = 4*10cm = 40cm
perimeter of square = perimeter of rect. = 2(l+b) = 40
If,
2(l+b) = 40
l+b = 40/2 = 20
12 + b = 20
b = 20-12 = 8
Area of square = 10*10 = 100cm^2
Area of rectangle = 12 * 8 = 96cm^2
