Answer:

since diagonal are equal of rectangle

QS=RT

4x+6=6x-4

6+4=6x-4x

2x=10

x=10/2

x=5

now

diagonal :4x+6=4*5+6=26

Step-by-step explanation:

Diagonals of rectangle are equal

[tex]\\ \tt\longmapsto 4x+6=6x-4[/tex]

[tex]\\ \tt\longmapsto 4x-6x=-4-6[/tex]

[tex]\\ \tt\longmapsto -2x=-10[/tex]

[tex]\\ \tt\longmapsto x=5[/tex]

  • QS=RT=4(5)+6=26units[/tex]
