Answer:
The answer is 20 meters squared
base area = side^2 = 2^2 = 4 m^2
base perimeter = (2 x 4) = 8 m
lateral surface = (base perimeter x slant height)/2 = (8 x 4)/2 = 16 m^2
surface area = (base area + lateral surface) = (4 + 16)= 20m^2
Answer:
<u>4</u>
Step-by-step explanation:
Hi so basically you just convert the inches to decimals so
0.5 x 0.5 x 0.25 = 0.0625
Use a calculator to convert 0.0625 into fraction which is 
Multiply 
by 3 = 
Then multiply by = 4
Soo that was probably very confusing, but I hope it helps! :)

Answer:
x= 32.3 (3 s.f.)
θ= 21.8° (1 d.p.)
α= 68.2° (1 d.p.)
Step-by-step explanation:
Applying Pythagoras' Theorem,
x²= 12² +30²
x²= 144 +900
x²= 1044
Square root both sides:
x= 32.3 (3s.f.)
θ= 21.801° (3 d.p.)
θ= 21.8° (1 d.p.)
= 68.2° (1 d.p.)
Alternatively,
α +θ +90°= 180° (∠ sum of triangle)
α +21.801° +90°= 180°
α +111.801°= 180°
α= 180° -111.801°
α= 68.199°
α= 68.2° (1 d.p.)

Answer:
The second option, 1,008 cm²
Step-by-step explanation:
This shape has 5 sides to solve for with reguards to surface area.
Let us solve for them all.
[1 & 2 - the triangles]
12 * 9 = 108 cm²
-> I am not going to divide since we have 2 congruent triangles
[3 - the bottom side]
25 * 12 = 300 cm²
[4 - the side facing away]
25 * 9 = 225 cm²
[5 - the side facing up]
25 * 15 = 375 cm²
Now we will add them together for the total.
108 + 300 + 225 + 375 = 1,008 cm²
The surface area for the triangular prism shown is 1,008 cm².
