1092cm².
Answer:
Solution given:
First Side (a)= 18cm
Second side (b)=8cm
length(l)=15cm
height(h)=12cm
slant height (c and d)=13cm
Now we have
Total surface area of the trapezoid prism
=2 × area of base + lateral surface area
=2*area of trapezoid +perimeter of trapezoid*length =2*½*h*(a+b)+(a+b+c+d)*l
=12(18+8)+(18+8+13+13)*15
=1092 cm^2
Total surface area of the trapezoid prism is <u>1</u><u>0</u><u>9</u><u>2</u><u>c</u><u>m</u><u>²</u><u>.</u>
Answer:
300 meters away
Step-by-step explanation:
it will take the dolphin 50 seconds to finish the race( 400/8 )
it will take the man 200 seconds to finish the race( 400/2 )
by the time the dolphin crosses the finish line it will take the swimmer 150 seconds to reach the finish line (200 - 50 seconds)
recall the swimmer swims at 2 meters per second and has 150seconds to reach the finish line hence he is 300 meters away ( 150 x 2)
