Question

ayuda porfavor es urgente :c si no saben no contesten

Answer 1

La priemra

$A = \frac{base(altura)}{2}\\\\A = \frac{4 cm(6cm)}{2}\\\\A = \frac{24cm^{2})}{2}\\\\A = 12 cm^{2}$

La segunda

A = Base(altura)

A = (10cm)(7cm)

A = 70 cm²

La cuarta

$A = \frac{(basemayo+basemenor)(h)}{2}\\\\ A = \frac{(12+6)(8)}{2}\\\\A = \frac{(18)(8)}{2}\\\\A = (9)(8)\\\\A = 72 cm^{2}$
