Answer:
16 = l
4 = w
Step-by-step explanation:
{64 = wl
{40 = 2w + 2l
{l = 8 + 2w
64 = w[8 + 2w] ↷
-64 + 8w + 2w² ↷
[2w² - 8w] + [16w - 64]
2w[w - 4] 16[w - 4]
[w - 4][2w + 16] = 0
↑
This is the expression we want because when we talk about dimensions, we want NON-NEGATIVE numbers. The other expression results in -8 = w, and we do not want that; this expression gives us a solution of 4 = w, and THIS is exactly what we want. Anyway, you plug "4" back into the system of equations and you will get a length of 16 centimetres.

Hey there!
10 * 8 = 8 * e
10 * 8 = 80
80 = 8 * e
8 * e = 80
8e = 80
DIVIDE 8 to BOTH SIDES
8e/8 = 80/8
CANCEL out: 8/8 because that gives you 1
KEEP: 80/8 because that gives the value of x
x = 80/8
80/8 = x
10 = x
x = 10
Therefore your answer is: 10
Because, 10 * 8 = 8 * 10
Good luck on your assignment and enjoy your day!
