I don’t know the answer for sure but i do know for surface area you multiply all the sides together so maybe that will help you. (you would count how many units they go over for each line.)
Rewrite it in the form a^2 - b^2, where a = 2x and b = 5
(2x)^2 - 5^2
Use the Difference o Squares: a^2 - b^2 = (a + b)(a - b)
<u>(2x + 5)(2x - 5) </u>
The diagonal's length is about 3.5 inches; to solve, use the Pythagorean theorem (a^2 + b^2 = c^) to determine the length of the diagonal using one of the two triangles it forms by cutting the square in half. One triangle has three sides: 6 in, 6 in, and the unknown diagonal.
6^2 + 6^2 = c^2 Plug in the known sides
36 + 36 = c^2 Simplify
72 = c^2 Simplify
~3.5 = c Take the square root of both sides
