What is the base perimeter of a rectangular prism which is formed by joining two identical right triangular prisms? It is given that each right triangle has a height of 2 m and base 4 m.
Base perimeter of a rectangular prism=2×(right triangle′s height+right triangle′s base)
⇒ Base perimeter of the rectangular prism=2×(2+4)
⇒Base perimeter of the rectangular prism=2×6=12 m
