Question

The perimeter of Rectangle is 100cm. the length of rectangle is 10 cm more than its breadth
find length and breadth of rectangle

Answer 1

Answer:

Let length of rectangle =x

Breadth of rectangle =x−10

∴ Perimeter = 2(l+b)=2(x+x−10)

2(2x−10)=100,

⇒2x−10=50

⇒2x=60

⇒x=

2

60

=30

Length =30 cm

Breadth =30−10=20 cm.

Answer 2

perimeter of the rectangle =2(l+b)

30=2(10+b)

30/2=10+b

15=10+b

15-10=b

5cm=b

10cm=l
