HELP THIS IS DUE TODAY AND I NEED THIS DONE

Answer 1

1240 cm2 because surface area of the triangular prism

Answer 2

1240 cm²

Explanation:

Surface area of triangular prism:

`\boxed{\text{\bf Surface area of triangular prism = bh + (s_1+s_2+s_3)*l }}`

`\boxed{ \text{ \bf Surface area of triangular prism = $ \bf bh + (s_1+s_2+s_3)*l$ }}`

b = base of the triangle = 16 cm

h = altitude of the triangle = 15 cm

s1 , s2 ,s3 are the edges of the triangle

s1 = 16 cm ; s2 = 17cm ; s3 = 17 cm

l = length of the rectangle = 20 cm

Surface area = 16*15 + (16 + 17 + 17)*20

= 240 + 50*20

= 240 + 1000

= 1240 cm²
