Okay yes i need a lot of help okay

either 78.4cm or 288.4cm

Step-by-step explanation:

rectangle area

A = 15x4

A = 60

Area of 2 triangles

A = 4.6x4/2

A = 9.2x2

A = 18.4

18.4 + 60 = 78.4cm

Maybe the answer

Area of 2 rectangles

A = 15x4

A = 60

A = 15x14

A = 210

Area of 2 triangles

A = 4.6x4/2

A = 9.2x2

A = 18.4

60 + 210 + 18.4 = 288.4cm

either answer hope one is right

228.4

Step-by-step explanation:

Both triangle surface:

4x4.6 and then divide by 2 = 9.2

That will be the surface for one triangle

But there are two triangles so we times that by 2

That will be 18.4

Both big rectangle surface: (the top and bottom ones)

15x5=75

But we have two rectangles

So we times that by two and the answer will be =150

Smaller rectangle: (the one between two triangles)

4x15=60

Okay, now we add them all up, the triangles and rectangles

60+150+18.4=228.4
