Question

the perimeter of a rectangle is 100cm and its length is 30cm. What is the breadth of the rectangle?. What is the area of the rectangle?

Answer 1

Hi THERE!!!

Given : - Perimeter of rectangle = 100 cm,
length = 30 cm

Perimeter of rectangle = 100 cm

2 ( l + b ) = 100

2 ( 30 + b ) = 100

30 + b = 100/2

30 + b = 50

b = 50 - 30

b = 20

Breadth of rectangle = 20 cm

Area of rectangle = l × b

= 20 × 30

$= {600 \: cm}^{2}$

HOPE IT HELPS U :))

Answer 2

Answer:

Given : - Perimeter of rectangle = 100 cm,

length = 30 cm

Perimeter of rectangle = 100 cm

2 ( l + b ) = 100

2 ( 30 + b ) = 100

30 + b = 100/2

30 + b = 50

b = 50 - 30

b = 20

Breadth of rectangle = 20 cm

Area of rectangle = l × b

= 20 × 30

= 600CM²
