Can you please provide the solutions. thank you

#6 is 36

Perimeter = 2L + 2W = 26

2(x+5) + 2(x) = 26

2x+10 + 2x = 26

4x+10=26

4x = 26-10

4x = 16

x=4

Subsitute x to formula

2(x+5) + 2(x) = 26

2(4+5) + 2(4) = 26

2(9) + 8 = 26

18+8 = 26

26=26

length = 9

width = 4

Area of Rectangle = L xW

9×4 = 36

can you please provide the solution for #10? tnx
