<span>lengths are in ratio 1:3
areas are in ratio
1 : 3</span>²<span> = 1: 9

Which steps can be used to solve for the value of 'y'? 2/3(y+57)=178

bagirrra123 [75]

2 / 3 ( y + 57 ) = 178

2( y + 57 ) / 3 = 178

2*y + 2 * 57 / 3 = 178

2y + 114 / 3 = 178

3*(2 y + 114 ) / 3 * ( 178)

2 y + 114 = 534

2y = 534 - 114

2 y = 420

y = 420 / 2

y = 210

hope this helps!
