Answer:
ans:- 14
Step-by-step explanation:
let length = x
so, width= 2x -1
perimeter= 2(l +b)
82 = 2(x+ 2x-1)
41 = 3x - 1
3x = 42
x = 14

Answer:
Step-by-step explanation:
eq. of line through (-4,0) and (3,2) is
y-0=(2-0)/(3+4) (x+4)
y=2/7 (x+4)
or y=2/7 x+8/7
m1=2/7
b1=8/7
eq. of line through (-3,2) and (4,0) is
y-2=(0-2)/(4+3) (x+3)
y-2=-2/7(x+3)
y=-2/7 x-6/7 +2
or y=-2/7 x+8/7
m2=-2/7
b2=8/7
m1b2+m2b1
