Step-by-step explanation:

12 times 4 + 12 + 48

Answer:

Not sure but giving it a try.

the perimeter of a circle is its circumference. C=2pir

2×3.142×6=38cm

the perimeter of one triangle is 13cm+5cm+12cm. how did i get 5?

22-12=10,

10÷2=5.

13cm+5cm+12cm= 30.

count that as two, 30+30=60.

perimeter of square= length × 4 = 12×4 = 48

Total : 38cm+60cm+48 = 146cm?
