3v wedding photography lawn

Suppose the lawn is x meters wide and x meters long.

He × [(he x+ he) x e]+he x x e = 64，

He x [he x+ he]+he x=64，

4x+4+ he x=64，

6x=64-4，

x=60÷6，

X= person,

Man× He =e0 (m)，

Person× E0 = person 0 (square meter) = person 00000 square centimeters.

This lawn covers an area of 00,000 square centimeters.
