Answer:
70
Step-by-step explanation:
30+40=70 and anything times 1 is the same #
The surface area of the prism will be given by:
SA=(surface area of triangles)+(surface area of rectangles)
surface area of triangles=2(1/2*3*4)=12 sq. units
area rectangles
the length of the hypotenuse will be:
c²=a²+b²
c=√(3²+4²)
c=√25
c=5
area=(3*5)+(4*5)+(5*5)=60
Total area=60+12=72 sq. units
Answer: 72 sq. units
<span>Parallelogram area = height × base
</span>
<span>Parallelogram height = area / base
</span>
<span>Parallelogram height =136 / 16
</span>
<span>Parallelogram height = 8.5 meters

There is an app to tell you the answer
A=-9
The work:
2 (A+24)=30
Multiply 2 by 24 and A so u get
2 +24=30
Then subtract 48 from both sides to get
2A=-18
Then divide by 2 to get
A=-9
