Answer:
24.4
Step-by-step explanation:
18 ÷ 2 = 9
26² = x² + 9²
x² + 81 = 676
x² = 676 - 81
x² = 595
x = √595
x ≈ 24.4

I round the answer to the second digit and get 18.33
Area of rectangle = 15 x 8
=120
area of parallelogram = 8 x 15
=120
so, they have the same area, because the length of a rectangle is the same as the height of a parallelogram and also for the base.
