Question

Calculati aria dreptunghiului cu laturile de:$( \sqrt{3} +3)cm,si ( \sqrt{27} +2)cm$

Answer 1

[tex]A = L*l \\ L=(\sqrt{27} +2 ) cm\\ L= (3 \sqrt{3} +2)cm \\ (l= \sqrt{3}+3)cm \\ A= (3 \sqrt{3} +2)cm * ( \sqrt{3}+3)cm \\ A=(9 + 9 \sqrt{3} + 2 \sqrt{3} + 6 ) cm^2 \\ A= (15+ 11 \sqrt{3}) cm^2 [/tex]
