Im not sure if this answers your question, there isn't much detail.
If we were to do the distrubitive property -- 7y+42
C. $2919.97
Y1 $2400 x.04 =96
Y2$2496 x.04 =99.84
Y3$2595.84 x.04 =103.86
Y4$2699.67 x.04= 107.99
Y5$2807.66 x.04= 112.31 = Total $2919.97
If the perimeter is 26 and the length of one side of the rectangle is 5cm longer than its breadth,
26 - 5 - 5 = 16
16 / 4 = 4 ( rectangle has 4 sides. )
the breadth is 4cm.
so the length must be 4+5=9cm.
