Question

Calcule a área do quadrado sabendo que o lado mede (2p + 6). preciso do calculo

Answer 1

Quadrado da soma de dois termos

$\large\boxed{\boxed{\boxed{\boxed{\mathsf{(a+b)^2=a^2+2ab+b^2}}}}}$

Área do quadrado de lado $\huge\mathsf{\ell}$

$\huge\boxed{\boxed{\boxed{\boxed{\mathsf{A=\ell^2}}}}}$

$\dotfill$

$\mathsf{\ell=2p+6}\\\mathsf{A=\ell^2}\\\mathsf{A=(2p+6)^2}\\\mathsf{A=(2p)^2+2\cdot2p\cdot6+6^2}\\\large\boxed{\boxed{\boxed{\boxed{\mathsf{A=4p^2+24p+36}}}}}$
