Let the breadth = x and length =2x+2 As we know peri. Of rectangle =2×(l+b) A/Q. 154= 2(2x+2+x) 154÷2=77-2=75 75=2x+x=3x 75÷3=25=x Then breadth is 25 And length is 25×2=50+2=52 ?????

Let length be x+2 And breadth be 2x Perimeter of rectangle=2[L+b] A.T.Q 154=2[x+2+2x] 154= 2[3x+2] 154/2=3x+2 77=3x+2 77-2=3x 75=3x 75/3=x 25=x
