Let's find the area of the base.
It's a rectangle that's 3.8 by 4.8, so let's multiply.
3.8×4.8=18.24
We have two different triangles.
Triangle one has a height of 2.6 and base of 4.8. But there are two of them.
2.6×4.8×0.5=6.24×2= 12.48; this is the area of two triangles.
Another set of triangles has a height of 2.9 and a base of 3.8.
2.9×3.8×0.5=5.51×2=11.02
Let's add all the areas together.
18.24+12.48+11.02
41.74
The surface area is 41.74 m², so the third option.
Firstly, the best thing to do is to expand the bracket.
To expand, you multiply everything at the front of the bracket by everything inside of the bracket.
4(s+2) becomes 4s (4*s) = 8 (4*2)
Then put this back into the equation, and this becomes;
4s+8+s-1
Then collect the like terms (these are the similar ones)
4s+s becomes 5s
8-1 becomes 7.
Therefore, the simplified equation is 5s+7
Hope this helps :)
