Answer 1

hope you understand..

Answer 2

Step-by-step explanation:

perimeter of square = perimeter of rectangle

peeimeter of square = 8×4 =32

perimeter of rectangle = 2(l+b)

as perimeter are equal

32 = 2(l+b)

32 = 2(l+5)

32÷2 = l+5

16 = l+5

16-5 = l

11cm = lenght

area of rectangle = l×b

= 11 × 5 = 55cm^2
