Question

the perimeter of the rectangular field is equal to the perimeter of the square field of side 16.5 cm. If the lenght of the rectangular field is twice the breadth, find the lenght and breadth of the rectangular field.

Answer 1

let l=x
Then b=2x
2(l+b)=4a
2(x+2x)=4*16.5
6x=33/5
X=33/5*1/6
x=33/30
x=1.1 cm


Then,
L=x=1.1 cm
&
b=2x=2*1.1=2.2 cm

Answer

Answer 2

Perimeter of rectangular field = perimeter of square feild
2(l+b) = 4× side of square
2 × 3b = 4× 16.5[ l = 2b]
6b = 66
[b = 11]
l = 2b
Therefore,
[l = 22]
