Question 1209447
<font color=black size=3>
L = unknown length
W = 8 is the width


P = perimeter of the rectangle
P = 2*(L+W)
2(L+W) = 26
2(L+8) = 26
L+8 = 26/2
L+8 = 13
L = 13-8
L = <font color=red>5</font>


Another way to solve
2(L+8) = 26
2L+16 = 26
2L = 26-16
2L = 10
L = 10/2
L = <font color=red>5</font>


The rectangle is 8 cm wide and <font color=red>5 cm</font> tall.
