300 x 700 = 210,000 square feet
600 x 1400 = 840,000 square feet
840,000 - 210,000 = 630,000 square feet difference

Answer:
927 ft
914 ft
Step-by-step explanation:
The lengths are half the sum plus or minus half the difference:
1841/2 ± 13/2 = {1854/2, 1828/2} = {927, 914} . . . feet
__
Let x represent the shorter length. Then x+13 is the longer length. Their total is ..
x +(x +13) = 1841
2x = 1841 -13
x = (1841 -13)/2 . . . . half the sum minus half the difference
Then the longer length is ...
x+13 = (1841/2) -(13/2) +13
x +13 = (1841/2) +(13/2) . . . . half the sum plus half the difference
