Q 11​

Answer 1

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 2

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
