Question

The length of rectangle field is thrice breath the it’s Perimeter is 400 m find its breath and the length

Answer 1

Answer:

length =150m and breadth =50m

Step-by-step explanation:

let

breadth =x

2 (x+3x) =400m

2×4x=400m

8x=400m

x=400m /8

x=50m

length = 3x = 3×x

length =150m

Answer 2

Step-by-step explanation:

Length of field =3xm

Breadth of field =Xm

perimeter of rectangle=2(l+b)

from formula

400= 2(l+b)

or 400 =2(3x+x)

or 400 = 2×4x

or 400 = 8x

: 400 /8 =x

50=x

so x =55m

Now

Length = 3x

3×50

160m

Breadth = Xm

50m
