Question

the length of a rectangle is 8cm more than its breadth. if the perimeter of a rectangle is 44cm find the length and breadth of the rectangle?​

Answer 1

Answer:

length=15 and breath=7

Step-by-step explanation:

let length be x and breath be y

then by condition given

x=8+y

perimeter=2(l+b)

44=2(x+y)

44=2(8+y+y)

44=2(8+2y)

44/2=8+2y

22=2(4+y)

11=4+y

y=11-4 =>y=7

x=8+7=15

Answer 2

Let, breadth of the rectangle be x cm, the length will be (x+8)cm.

Perimeter of rectangle= 2(l+b)

44 = 2(x+8+x)

44/2 = 2x+8

22 = 2x+8

22-8 = 2x

14 = 2x

x = 14/2

x = 7

Length of rectangle is (x+8)cm= 15 cm

Breadth of rectangle is 7 cm
