Question

Uh i need help bc i cant get the question correct

Answer 1

Step-by-step explanation:

just take a deep breath, shake your limbs, and then focus on it again.

the surface consists of 5 areas :

front and back triangles (2)

left rectangle

right rectangle

floor rectangle

the area of a rectangle is simple :

length × width

the area of a triangle is

baseline × height / 2

each of the front and back triangles has an area of

5 × 4 / 2 = 5×2 = 10 cm²

both of them have then 10×2 = 20 cm²

the left rectangle is

9×6 = 54 cm²

the right rectangle is

9×5 = 45 cm²

the floor rectangle is also

9×5 = 45 cm²

so, the total surface area is

20 + 54 + 45 + 45 = 164 cm²

Answer 2

Answer:

164

Step-by-step explanation:

Finding the Surface Area :

• Area (2 triangles) + Base rectangle + Left rectangle + Right rectangle
• 2 x 1/2 x 4 x 5 + 9 x 5 + 6 x 9 + 5 x 9
• 20 + 45 + 54 + 45
• 65 + 99
• 164 cm²
