Question

Please I’m struggling

Answer 1

1080 cm

Explanation:

To find the surface area, you must find the area of each shape then add all of them together which will give you the surface area.

First, multiply the big rectangle on the top which is: 14cm x 26cm= 364

Next find the area of the triangles which is: 24cm x 10cm= 240/2= 120

Since there is two triangles, u must multiply 120 by 2 which is 240

the rectangle from behind is 10cm x 14cm= 140cm

and the last rectangle on the bottom is 14cm x 24cm= 336cm

Now you must add all of these together: 364 + 240 + 140 + 336 which is 1080.

Answer 2

1080cm²

Explanation:

surface area=sum of the area of all the shapes

area of triangle=1/2*base*height

1/2*24*10=120*2(because there are two triangles)=240cm²

10*14=140cm²

24*14=336cm²

Area of slanting figure=26*14=364cm²

add all the results

240+140+336+364=1080cm²
