Question

The area of a rectangle is 650 cm2. If its breadth is 13 cm, then its perimeter is
Yi) 50 cm
(ii) 63 cm
(iii) 126 cm
(iv) 226 cm​

Answer 1

Step-by-step explanation:

Area of rectangle = length * breadth

length * 13 = 650

length = 50

now we have length = 50 cm

and breadth = 13 cm

so perimeter of rectangle= 2(l+b)

2(50+13)

2(63)

126

the correct answer is 126

Answer 2

☆ Solution ☆

Given :-

• The area of a rectangle is 650 cm².
• The breadth of rectangle is 13 cm.

To Find :-

• Perimeter of the rectangle.

Step-by-Step-Explaination :-

As we know that :-

Area of rectangle = l × b

Where,

• Area of rectangle = 650 cm²

• l = l

• b = 13 cm

Putting the respective value,

650 = l × 13

650 = 13 l

l = 650/13

l = 50

Thus,

The length of rectangle = 50 cm

Now,

As we know that :-

Perimeter of rectangle = 2 ( l + b )

Where,

• l = 50 cm

• b = 13 cm

Putting the respective value,

Perimeter of rectangle = 2 ( 50 + 13 )

Perimeter of rectangle = 2 × 63

Perimeter of rectangle = 126

Thus,

The perimeter of rectangle = 126 cm

Hence,

Option iii) 126 cm is correct option.
