Question

Q5. Find the perimeter of rectangle whose area = 169 cm
and L = 13 cm.​

Answer 1

Answer:

52 cm

Step-by-step explanation:

Breadth of rectangle = area / length

=169/13=13 cm

perimeter of rectangle=2(l+b)

=2(13+13)

2×26

52cm

Answer 2

Given :

• Area of rectangle = 169 cm² .
• Length of rectangle = 13 cm .

To Find :

• Perimeter of the rectangle .

We know that :

Area of rectangle = Length × Breadth

→ 169 = 13 × Breadth

→ 169/13 = Breadth

→ Breadth = 13 cm

Now we have,

• Length = 13 cm
• Breadth = 13 cm

Both length and breadth are equal. So, this is a square .

Perimeter of rectangle = 2(L + B)

→ 2(13 + 13)

→ 2 × 26

→ 52 cm

Also finding its perimeter as square

Perimeter of square = 4 × side

→ 4 × 13

→ 52 cm

Perimeter of the rectangle is 52 cm .
