Question

1. The length of a rectangular field is
8 meters
less than twice its breadth
De the perimeter of the rectangular
field is 56 meters, find its con
the rectangular
length and breadth​

Answer 1

Answer:

Step-by-step explanation:

let breadth=x, then length=2x-8

then 2(2x-8+x)=56

2(3x-8)=56

6x-16=56

6x=56+16

6x=72

x=12

breadth =x=12, length =24-8=16

Answer 2

Answer:

let the breadth of rectangle(b) = x m

then length(l) = (2x-8) m

A/q,

     perimeter of rectangle = 56 m

⇒  2(l+b) = 56

⇒  2(2x-8+x) = 56

⇒    3x-8 = 28

⇒     3x =28+8

⇒     x = 36/3 = 12 m

therefore length(l) = 2x-8 =2×12 - 8 =16 meters

              breadth(b) = x = 12 meters
