Answer 1

Step-by-step explanation:

Perimeter of rectangle=59.1c.m

Breadth=13.8cm

Perimeter of rectangle=2(l+b)

59.1=2(l+13.8)

59.1=2l+27.6

59.1-27.6=2l

31.5=2l

31.5÷2=l

15.75=l

The length of rectangle =15.75

Answer 2

Answer:

15.75

Step-by-step explanation:

perimeter = 59.1

2(l+b)=59.1

2(l+13.8)=59.1

l+13.8=59.1÷2

l=59.1/2-13.8

l=(59.1-27.6)÷2

l=31.5÷2

l=15.75
