Final answer:
To calculate the area Kira planted with corn, multiply 3/5 by 3/7, which equals 9/35 acres.
Step-by-step explanation:
Kira's corn planting area can be calculated by multiplying the fraction of her land planted with corn, 3/7, by the total land she owns, which is 3/5 acres. To compute this, you multiply the numerators (3 × 3) to get 9, and the denominators (5 × 7) to get 35. Therefore, Kira planted 9/35 acres of her land with corn. This fraction represents the proportion of her total land dedicated to corn cultivation. The multiplication process allows us to determine the specific area allocated for corn in relation to her total land, yielding a fraction that signifies the fraction of the total area occupied by corn cultivation.
