Rect=2(l+b)
=2(2x+x) =28
=4x+2x=28
After this answer is x=4.66

Darkmatter: Hey friend wrte you go

silki134: First is A

Darkmatter: Oo

silki134: Bye good night

let the breadth be 'x'
=> length = 2+2x
perimeter of RECTANGLE = 2(l+b)
28 = 2(2+2x+x)
14 = 2+3x
14-2 = 3x
3x = 12
X = 4

mili183011: Call length and breadth, L and B.
Thus L = 2B + 2
Also perimeter P = 2L + 2B = 28
Substitute the first equation into the second and get

2(2B + 2) + 2B = 28
4B + 4 + 2B = 28
6B + 4 = 28
6B = 24
B = 4
L = 10

Darkmatter: Heu mili how come 10 please give me answer
