Answer:

$SA=41.74\ m^2$

Explanation:

we know that

The surface area of the rectangular pyramid is equal to the area of its rectangular base plus the area of its four triangular faces

so

step 1

Find the area of its rectangular base

A=(4.8)(3.8)

$A=18.24\ m^2$

step 2

Find the area of its four triangular faces

A=2[(1)/(2)(4.8)(2.6)]+2[(1)/(2)(3.8)(2.9)]

$A=12.48+11.02=23.5\ m^2$

step 3

Find the surface area

Adds the areas

SA=18.24+23.5

$SA=41.74\ m^2$
