Question

4. Find the perimeter of rectangle whose length and breadth are 12.57 cm and 8.09 cm.
​

Answer 1

GIVEN:

• Length of rectangle = 12.57 cm
• Breadth of rectangle = 8.09 cm

TO FIND:

• What is the perimeter of rectangle ?

SOLUTION:

Let the perimeter of rectangle be 'P' cm

To find the perimeter of rectangle, we use the formula:-

❰ P = 2[LENGTH + BREATH] ❱

• Length = 12.57 cm
• Breadth = 8.09 cm

According to question:-

On putting the given values in the formula, we get

➙ P = 2(12.57 + 8.09)

➙ P = 2 $\times$ 20.66

❮ P = 41.32 cm ❯

❝ Hence, the perimeter of the rectangle is 41.32 cm ❞

Answer 2

Step-by-step explanation:

= perimeter of rectangle = 2×( L + B )

= 2× ( 12.57 + 8.09 )

= 2× 20.66

= 41.32

Answer = 41.66
