Step-by-step explanation:

use formulas

Answer 2

#a

$\\ \sf\longmapsto H=\dfrac{√3}{2}a$

$\\ \sf\longmapsto H=dfrac{√3}{2}10$

$\\ \sf\longmapsto H=5√3in$

#b

$\\ \sf\longmapsto a=\dfrac{Diagonal}{√2}$

$\\ \sf\longmapsto a=\dfrac{√242}{√2}$

$\\ \sf\longmapsto a=\dfrac{11√2}{√2}$

$\\ \sf\longmapsto a=11in$
