Answer:

Step-by-step explanation:

surface area of a square base pyramid = base area + 4 ( triangular sides area)

where:

base = 11 m

side height length = 10 m

Surface area = 11² + 2(11)10

= 121 + 220

= 341 m²

Answer:

$\frac{ {x}^{2} }{y(x - y)} + \frac{ {y}^{2} }{ - x(x - y)}$

$\frac{ {x}^{2} }{y(x - y)} - \frac{ {y}^{2} }{x(x - y)}$

$\frac{ {x}^{2} \times x - {y}^{2} \times y}{xy(x -y)}$

$\frac{(x - y)( {x}^{2} + xy + {y}^{2}) }{xy(x - y)}$

$\frac{ {x}^{2} + xy + {y}^{2} }{xy}$
