1. Encontrar el área y perimetro de las siguientes figuras.
​

Answer 1

Figura 1

p=L+L+L+L = 9+9+9+9= 36

p=36cm

A= LxL= 9x9= 81

A=81 cm2

Figura 2

P= L+L+L+L =7.5+7.5+7.5+7.5= 30

P=30cm

A=LxL= 7.5x7.5= 56.25

A= 56.25cm2

Figura 3

P=L+L+L+L= 14+14+3+3=34

P=34 cm

A=bxh= 14x3= 42

A=42cm2

Figura 4

P=L+L+L+L= 8.2+8.2+3.5+3.5= 23.4

P=23.4cm

A= bxh= 8.2x3.5= 28.7

A=28.7cm2

Figura 5

P= L+L+L= 12+12+12= 36

P=36cm

A=bxh÷2= 12×8=96÷2= 48

A=48cm2

Figura 6

P=L+L+L= 10.5+10.5+10.5= 31.5

P=31.5cm

A=bxh÷2= 10.5x8.5=89.5

A=89.5cm2
