Question

The perimeter of a rectangular sheet is 100 cm if the length is 35 cm, find its breadth. Also find the area.​

Answer 1

Answer:

Let length= 1, breadth= of rectangle

→ Perimeter= 2(1+ b)

> 100 = 2(35 + b)

» 50 = 35 + b

» b = 15cm

Area= lb = 35 x 15 = 525cm

Answer 2

Answer:

the perimeter of a rectangular sheet = 100 cm

=>2(l+b) =100

=>2(35+b)=100

=>35+b=100/2

=>35+b=50

=>b=50-35

=>b=15 cm..

area of rectangular sheet=l×b

=35×15

=525cm sq
