The perimeter is 52 cm while the sum of non parallel sides is 20cm so the sum of parallel sides is 32cm
Now area of trapezium is 1/2 × sum of parallel sides × height
→1/2 × 32 × 8 =128 cm^2
Now area of trapezium is 1/2 × sum of parallel sides × height

Sorry the sum of parallels sides are 32 and hence 1/2×32×8=128
