I have already answered it

We first divide the big shape into smaller shapes

We get a trapezium and a triangle

We add the areas of the trapezium and the triangle together to get the total area of the big shape
It would be:

Area = area of trapezium + Area of triangle
         =[tex] \frac{1}{2} [/tex] × 5 (14 + 18) + [tex] \frac{1}{2} [/tex] × 12 × 18
         = 80  +  48  
         = 128 mm²
