whose side is (7x - 8) cm is:

O (28x - 8) cm
O
(28x - 32) cm
O 2 (7x - 8) cm
O (7x - 32) cm​

Answer 1

Answer:

(28x-32)cm is the answer

Answer 2

$\boxed{\mathsf \blue{perimeter \: = \: sum \: of \: all \: sides \: of \: a \: polygon}} \\ \\ \mathsf \red{given \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: } \\ \\ \mathsf{side \: of \: a \: square \: = \: 7x - 8} \\ \\ \mathsf \red{perimeter \: of \: square \: = \: 4 \times side} \\ \\ \mathsf {perimeter \: = \: 4(7x - 8)} \\ \\ \boxed{\mathsf{perimeter \: = \: 28x - 32}}$
