Question

.The perimeter of a rectangular sheet is 120 cm. If the length is 50 cm,

find its breadth. Also find its area.​

Answer 1

Answer:

Breadth= 10 cm Area= 500 sq. cm

Step-by-step explanation:

Perimeter= 120cm

Length= 50cm

Breadth= x

Perimeter of rectangle= 2(l+b)

120= 2(50+ x)

120= 100+ 2x

2x= 120-100

x= 20/2

x= 10

Thus, the breadth of the rectangle is 10 cm.

Area of rectangle= l × b unit sq.

= 50×10

= 500 sq. cm

Answer 2

Answer:

AS

the perimeter of rectangular sheet = 120cm

length ,, ,, ,, = 50cm

breadth ,, ,, ,, = 120-50

= 70
