Here is your answer
Area of 2 triangular part
=2× (1/2 × 3 × 4)
=12 sq. units
Area of three rectangular parts= (l×b)
= 11×5 + 11×4 + 11×3
= 55+44+33
= 132 sq. units
Hence,
surface area of prism= 12+132
= 144 sq. units

Answer:
We can apply the formula for surface area of a rectangular prism here. i.e.
Step-by-step explanation:
A=2(l×w + h×l + h×w), where l is length, h is height and w is width.
As mentioned above, length = 12 cm, width = 8 cm and height = 6 cm.
Therefore
2(12×7+6×12+6×8)=2(84+72+48)=2(204)=408. So the surface area of the brick is 408 square centimetres.
<span>y = -2x + 19
y = x + 7
-2x + 19 = x + 7
x + 2x = 19 - 7
3x = 12
x = 4
</span>y = x + 7
y = 4 + 7
<span>y = 11

You can change mm into cm. Since 1 cm is equal to 100 mm, divide 500 by 100 to get 5 cm. Add 30 and 5 to get 35. The two line segments are 35 cm together.
