Step-by-step explanation:
since there is triangle , you use the formula
1/2 × b × h
as you can see the base is 6 and the height is 4, so
1/2 × b × h
= 1/2 × 6 × 4
=12
12 × 2 = 24 , you times by 2 because there is 2 triangle
There is also rectangle in the diagram, so you use the formula , length × breadth , the length is 8 and the breadth is 5, so
length x breath
= 5 × 8
=35
35 × 2 = 70 , times by 2 because you can see 2 rectangles with the same length and breadth
length x breath
= 8 × 6
= 48
this one is different because the length is 8 and the breadth is 6.
SA = 48 + 35 + 24
= 107 cm ²
