$\"\"$ <\/a>O toldo tem a forma de dois ret\u00e2ngulos justapostos, de dimens\u00f5es $2,5\\,m\\times 2,2\\,m$. Logo, a \u00e1rea do toldo \u00e9 ${{A}_{Toldo}}=2\\times (2,5\\times 2,2)=11\\,{{m}^{2}}$.
\n\u00ad<\/li>\n
A tenda tem a forma de um prisma triangular reto, de bases triangulares is\u00f3sceles e faces laterais retangulares, duas com dimens\u00f5es $1,7\\,m\\times 2,5\\,m$ e outra com as dimens\u00f5es $1,5\\,m\\times 2,5\\,m$.\n
A \u00e1rea de uma base \u00e9 ${{A}_{b}}=\\frac{1,5\\times 1,5}{2}=1,125\\,{{m}^{2}}$.<\/p>\n
A \u00e1rea lateral \u00e9 ${{A}_{L}}=2\\times (1,7\\times 2,5)+(1,5\\times 2,5)=12,25\\,{{m}^{2}}$.<\/p>\n
Portanto, a \u00e1rea total da tenda \u00e9 ${{A}_{Tenda}}=2\\times {{A}_{b}}+{{A}_{L}}=2\\times 1,125+12,25=14,5\\,{{m}^{2}}$.<\/p>\n<\/li>\n<\/ol>\n
