Need Help ASAP! I will make correct answer branliest

SA=736ft²

Step-by-step explanation:

First I like to start with the triangles

The reason why we would multiply the triangle area by two is because where finding the area of the triangle in the Back and in the front

then we go to the rectangles of the left and right

again because the numbers for the base and height of the two rectangles are the same we are going to times by two.

Then we going to find the area for the base of the triangular prism, which would be the bottom rectangle

there are no same shapes with the same base and height so where not going to multiply by two

now we add all the area that we found up

now we have 736ft and since where finding SA we square it

SA=736ft²

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
