Answer 1

Answer:100x-1280

Step-by-step explanation:area of square=side x side

Answer 2

Answer:

Square has equal sides so both lengths are same.

Solve like this

10x - 20 = 64 - 18x (as both lengths are same)

10x+18x -20 = 64

28x = 64+20

x = 84/28

x = 3

Length of one side = 10x-20

=10(3) -20

=30-20

=10

Area of square is side * side

=10*10

=100
