I want to know the answer to the following question:
How large was the land (in acres) that the institution was founded on?
All the background I'm provided with is that "Faced with their continuing inability to find a substantial site, the Companies were eventually persuaded by the Secretary of the Science and Art Department, General Sir John Donnelly (who was also a Royal Engineer) to found their institution on the eighty-seven acre (350,000 m²) site at South Kensington bought by the 1851 Exhibition Commissioners (for GBP 342,500) for 'purposes of art and science' in perpetuity.". Is that enough to answer the question?
Answer: yes
