Question

Find the surface area

Answer 1

the surface area of traingular is pH+2B

then we have to do Area of the Base

which is 1/2×2×3 =3

then we find the area of rectangular 10×4=40

then we do another area which is 10×4=40

then we add first area and second area which is 40+3=43×2=86

now we add 86+40

now we find

Total surface area=86+40=126

I hope it's correct

Answer 2

i got 172. i did was i did 4 times 10 which is 40 then times that by 3 which equals to 160 then did 3 times 4 which is 12 then added that
