#556.m^2#

First, divide it into rectangles.

#color(blue)( 2 (17 m * 10 m)# rectangles

#color(orange)(2 (10 m * 4 m)# rectangles

#color(red)(2 (17 m * 4 m)# rectangles

After that, multiply them out:

#color(blue)(2 (170 m^2) = 2*170 = 340 .m^2#

#color(orange)(2 (40 m^2) = 2* 40 = 80. m^2#

#color(red)(2 (68 m^2) = 2* 68 = 136. m^2#

Finally, add them together:

#rArrcolor(green)(340+80+136=556.m^2#

#556.m^2#

This figure is a cuboid

Surface area of a cuboid#=color(blue)(2(bl+hl+bh)#

Where

#color(red)(b=breadth,h=height,l=l##color(red)(eng##color(red)(th#

#color(orange)( :.h=4,l=17,b=10#

Substitute the values in the formula

#rarr2((10*17)+(4*17)+(10*4))#

#rarr2((170)+(68)+(40))#

#rarr2(278)#

#rArrcolor(green)(556.m^2#

Solution #=color(green)(ul bar (|556.m^2|)#
