Answer 1

☆ Solution ☆

Given :-

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

To Find :-

• The perimeter of the rectangle.

Step-by-Step-Explaination :-

As we know that :-

Area of rectangle = length × breadth

Where,

• Area of rectangle = 650 cm²

• Breadth of rectangle = 13 cm

Let,

• The length of rectangle be L .

Putting the respective value,

650 = 13 × l

650/13 = l

l = 50

Thus,

Length of rectangle = 50 cm

Now,

As we know that :-

Perimeter of rectangle = 2 ( length + breadth )

Where,

• Length = 50 cm

• Breadth = 13 cm

Putting the respective value,

Perimeter of rectangle = 2 ( 50 + 13 )

Perimeter of rectangle = 2 × 63

Perimeter of rectangle = 126 .

Thus,

Perimeter of rectangle = 126 cm

Hence,

Option 3) 126 cm is correct option.

Answer 2

Question :

➙ The area of a rectangle is 650 cm2 and one of its sides is 13 cm. Find the perimeter of the rectangle

Answer :

➙ 126 cm

• Step by step explaination :

Let one side of rectangle be 'x'

᠉ Area of rectangle = L × B

᠉ 650 = 13 × x

᠉ x = 650 / 30

᠉ x = 50

Therefore , one side of rectangle = 50

᠉ Perimeter of rectangle = 2 ( l + b )

᠉ 2 ( 13 + 50 )

᠉ 2 ( 63 )

᠉ 126cm

Perimeter of rectangle = 126cm
