Question

1
The perimeter of a rectangle is 110 cm. If its
breadth is 20cm, then find its length​

Answer 1

Answer:

2(l+B)

2(110+20)

2×130

260

Answer 2

Answer:

Let the length be x

breath=20cm

To find:

Since,

Perimeter of rectangle=110cm

Formula:

Perimeter of rectangle=2(l+b)

Substituting the values:

110cm=2(x+20cm)

110/5=x+20

55=x+20

x=55cm-20cm

x=35cm

Let's verify by substituting the length=35cm

110cm=2(35cm+20cm)

110cm=2(55cm)

110cm=110cm

Since,LHS=RHS

Hence,the given solution:

length=35cm
