Question

Hallar el perímetro y áreas
de las siguientes figuras.

Answer 1

Respuesta:

$a) Perimetro: \\ P = b + h + b + h \\ P = 3 + 5 + 3 + 5 \\ P = 16u \\\\ Area \\ A = b * h \\ A = 3 * 5 \\ A = 15u^{2} \\\\b) Perimetro: \\ P = 4l \\ P = 4 * 4 \\ P = 16u \\\\ Area: \\ A = l^{2} \\ A = 4^{2} \\ A = 16u^{2} \\ \\ c) Perimetro \\ P = 2l_{1} + 2l_{2} \\ P = 2 * 5 + 2 * 2.7 \\ P = 15.4u \\\\ Area \\ A = b*h \\ A = 2.5 * 5 \\ A = 12.5 u^{2} \\\\ d) Perimetro: \\ P = 4l \\ P = 4*4 \\ P = 16u \\\\ Area: \\ A = \frac{D*d}{2} \\ A = \frac{4*7}{2} \\ A = 14u^{2}$
