Answer 1

Respuesta:

que necesitas formula area o que

Answer 2

Explicación paso a paso:

Triangulo 1

a=7cm

h=7,5cm

b=?

b = √h^2 - a^2

b = √7,5cm^2 - 7cm^2

b = √56,25cm - 49cm

b = √7,25cm

b = 2,69cm

Area 1= (B*H)/2

B = 2,69cm

H = 7cm

A1 = (2,69cm*7cm)/2

A1 = 18,83/2

A1 = 9,41cm^2

Triangulo 2

a = 7cm

h = 11cm

b = 11cm - 2,69cm

b = 8,31cm

Area 2 = (B*H)/2

B = 8,31cm

H = 7cm

A2 = (8,31cm*7cm)/2

A2 = 58,17/2

A2 = 29,08cm^2

Area total = A1 + A2

Area total = 9,41cm^2 + 29,08cm^2

Area total = 38,49cm^2
