You need the radius of all the orbits
earth radius is 150 million km
1. 150 million x 10 = 1500 million
From the website below Saturn would be the closest at 1,429 million km
1,500,000,000 - 1,429,000,000 = 71,000,000 km = 7.1 * 10^7 km
I hope this helps :D
It is given that the triangle is isosceles right triangle . And in an isosceles right triangle the legs are equal . Let each leg be of x units. Now we use pythagorean identity, which is





So the length of each leg is 
I think it's 79.50 square units. there three triangles in the quadrilateral shape above with the areas given so add the areas together to get the answer
