Question

Find the lateral area of the regular prism with height h, if the base of the prism is: Equilateral triangle with the side 4 cm and h=2.5 cm

Answer 1

30 cm^2

Explanation:

Answer 2

Equilateral triangle with the side 4 cm and h=2.5 cm

In equilateral triangle all sides are equal

so all sides are equal in the base of the prism

lateral area of the prism = Perimeter of the base * height

Perimeter of the base equilateral triangle = side + side + side

lateral area of the prism =(side + side + side) * height

= (4+4+4) * 2.5

=
`30 cm^2`

lateral area of the prism =
`30 cm^2`
