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          =[latex] \frac{1}{2} [/latex] × 5 (14 + 18) + [latex] \frac{1}{2} [/latex] × 12 × 18          = 80  +  48            = 128 mm²
