If they are the dimensions of a rectangle then the perimeter is: 2*(26+16) = 84
4(21 + 4)
26 plus 46
-16+(-10) = -26
84 + 16 = 100
84 + 16 = 100
26 + 16 +16 = 58
It is 84+16 = 100.
If they are the dimensions of a rectangle then the perimeter is: 2*(26+16) = 84
If that is: 15+(26-6)*(7-84) then it works out as -1525
46
4(21 + 4)
40
26 plus 16 equals 42. This can be calculated by adding the two numbers together: 26 + 16 = 42.
26 plus 46
-16+(-10) = -26
48+84+84=216
