Mathematics
1 answer:
k0ka [10]1 year ago
7 0

Step-by-step explanation:

the area of this rectangle is

(10 + 2x)(8 + 2x) = 168

80 + 20x + 16x + 4x² = 168

4x² + 36x = 88

because for the whole length you need to add x twice (left and right). the same for the width (top and bottom).

x = 11

Double-check:

22+5 = 27                33-6= 27
