**Problem Statement:** Find the area of the surface defined by the equations: 1. \( x + y + z = 1 \) 2. \( x^2 + 8y^2 \leq 1 \) **Explanation:** - The first equation, \( x + y + z = 1 \), represents a plane in three-dimensional space. - The second inequality, \( x^2 + 8y^2 \leq 1 \), describes an elliptical region in the \(xy\)-plane. The ellipse is centered at the origin with the semi-major axis along the \(x\)-axis and the semi-minor axis along the \(y\)-axis. The length of the semi-major axis is 1, while the length of the semi-minor axis is \( \frac{1}{\sqrt{8}} \). To solve this problem, you would integrate over the region defined by the ellipse on the \(xy\)-plane to find the area of the surface on the plane \(x + y + z = 1\). The surface area can be calculated using a surface integral over the region of the ellipse.
