556.m^2556.m2

Explanation:

First, divide it into rectangles.

color(blue)( 2 (17 m * 10 m)2(17m10m) rectangles

color(orange)(2 (10 m * 4 m)2(10m4m) rectangles

color(red)(2 (17 m * 4 m)2(17m4m) rectangles

After that, multiply them out:

color(blue)(2 (170 m^2) = 2*170 = 340 .m^22(170m2)=2170=340.m2

color(orange)(2 (40 m^2) = 2* 40 = 80. m^22(40m2)=240=80.m2

color(red)(2 (68 m^2) = 2* 68 = 136. m^22(68m2)=268=136.m2

Finally, add them together:

rArrcolor(green)(340+80+136=556.m^2340+80+136=556.m2

556.m^2556.m2

Explanation:

This figure is a cuboid

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

Where

color(red)(b=breadth,h=height,l=lb=breadth,h=height,l=lcolor(red)(engengcolor(red)(thth

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|)
