Ответ:
just have to find the area of the whole thing (10×15), then subtract the small square that isnt a part of it. because the lines on the right side are all equal, they are all 5cm. so, 5×5 is the area of that. subtract 25 from 150. that's your answer. hope it helps :)

Step-by-step explanation:
Part A:
≥ stands for "at least" and d has to be "at least" 500,
hence d ≥ 500
