P = 2(4x - 4) + 2(8x - 10)
P = 8x - 8 + 16x - 20
P = 24x - 28

The perimeter of a rectangle is represented by the formula P = 2l + 2w, where l is the length and w is the width. So all you have to do is plug your given sides in for the l and the w. You get the formula P = 2(4x - 4) + 2(8x - 10), which can be multiplied out and simplified down to P = 24x - 28. That is your expression for the perimeter of the rectangle.

Let L=4x-4
& B=8x-10
so perimeter=2{4x-4+8x-10}
=2{12x-14}
= 24x-28 ans

P = 2 (L + w)
P = 2(4x - 4 + 8x - 10)
P = 2(12x - 14)
P = 24x - 28

l = 4x-4 and w =8x-10
p = 2w+2l = 8x-8+16x-20
p = 24x - 28
