The image that shows the reflection of DFEG over the x-axis is the FIRST option. The x-axis is the mirror line. The distance from the mirror line to the reflected shape equals to the distance from the original image to the mirror line.
Surface area is the sum of area of all surfaces.
In the given diagram , we have two identical triangles , with height = 20 cm and base = 25 cm. Area of triangle = (1/2)*base * height.
So for the given triangle , area = 2*(1/2)*20*25 = 500 cm square .
We have a bottom rectangle whose area is 25*40 = 1000 cm square. A sideby rectangle, whose area is 35*40= 1400 cm square and a backwards rectangle, whose area is 20*40 = 800 cm square.
So the surface area = 500+1000+1400+800 =3700 cm square.
