Question

The length of the rectangle is 4

2 + 5 − 3 cm and breadth is 2

2 + 4 − 1 . Find the

perimeter and area of the rectangle​

Answer 1

Given:

• Length of the rectangle = 42 + 5 – 3 cm = 44cm
• Breadth of the rectangle = 22 + 4 – 1 cm = 25cm

To find:

• Perimeter
• Area

Solution :

$perimeter \: of \: a \: rectangle \: = \: 2(l + b)$

= 2 ( 44 + 25 )

= 2 ( 69 )

= 138 cm

$area \: of \: a \: rectangle \: = length \: \times \: breadth$

= 44 x 25

= 1100 cm²

>> Perimeter = 138cm

Area = 1100cm²
