Question

determine a área do retângulo a seguir :

$base = \sqrt{15 } \: \: altura = \sqrt{8}$
​

Answer 1

Área do retângulo de base $\underline{\mathsf{\ell}}$ e altura h

$\huge\boxed{\boxed{\boxed{\boxed{\mathsf{A=\ell\cdot h}}}}}$

$\dotfill$

Dados:

$\mathsf{\ell=\sqrt{15}~~~h=\sqrt{8}=2\sqrt{2}}$

$\mathsf{A=\ell\cdot h}\\\mathsf{A=\sqrt{15}\cdot2\sqrt{2}}\\\huge\boxed{\boxed{\boxed{\boxed{\mathsf{A=2\sqrt{30}~u\cdot a}}}}}$
