40 acres= how many meters?

Janelle,

According to my dictionary one acre is 43560 square feet. Thus

1 acre = 43560 sq ft = 43560 12 12 sq inches

But one inch is 2.54 centimeters and there are 100 centimeters in a meter so

1 acre = 43560 12 12 2.54 2.54 sq cm
= 43560 12 12 2.54 2.54  ¹/₁₀₀   ¹/₁₀₀ = 4046.86 sq meters

Thus 40 acres is 40 4046.86 = 161874.26 square meters.
