Question

The perimeter of a rectangle is 17 cm and its width is 3 1/2 cm. Find its length

Answer 1

Answer:

length= -7

Step-by-step explanation:

The perimeter of rectangle=17cm

Breadth (width)=31/2

Length be x

17=2(x+31/2)

17/2=x+31/2

x=17/2-31/2

x= -14/2

x= -7

Length= -7

Answer 2

Answer:

l=5cm

Step-by-step explanation:

perimeter= sum of all sides

so p= 2 x l + 2 x w

so 17=2 x l + 2 x 3 1/2

17-7=2 x l

10= 2 x l

L= 2/10

l= 5
