Answer 2

answer

619.2 cm²

step - by - step explanation

we don't know what is the shape of cornfield

so,

we can use "heron's formula"

heron's formula = √(s - a)(s - b)(s - c)

a = 120 cm , b = 160 cm , c = 200 cm

where as "S" = (a + b + c)/2 = (120 + 160 + 200)/2 = 480/2 = 240 cm

put the value

= √(240 - 120)(240 - 160)(240 - 200)

=√ 120 × 80 × 40

= √2×2×2×3×5×2×2×2×2×5×2×2×2×5

= 2×2×2×2×2×5√3 × 5

= 160√15

= 160 × 3.87

= 619.2 cm²
