Answer:
l = 4, w = 14
Step-by-step explanation:
l - length;
w - width;
l = w - 10;
We substitute the 'l' using the previous formula =>
![[tex]A_r = (w -10) \cdot w = w^2 - 10w = 56 =>\\w^2 - 10w - 56 = 0\\](https://tex.z-dn.net/?f=%5Btex%5DA_r%20%3D%20%28w%20-10%29%20%5Ccdot%20w%20%3D%20w%5E2%20-%2010w%20%3D%2056%20%3D%3E%5C%5Cw%5E2%20-%2010w%20-%2056%20%3D%200%5C%5C)
By the quadratic formula we solve for 'w':(we will use the positive value, because we're talking about lengths of planes in a Euclidean space)
l = w - 10 = 14 -10 = 4
