Sagot :

Answer:

96cm

Step-by-step explanation:

front/back triangles: (4 * 3) / 2 = 6cm

bottom rectangle: 4 * 7 = 28cm

side rectangle (left): 3 * 7 = 21cm

slanted rectangle: pythagoras - 3^2 + 4^2 = x^2

9 + 16 = x^2

25 = x^2

square root of 25 = 5

x = 5

7 * 5 = 35cm

6 * 2 + 28 + 21 + 35 = 96cm
