Question Statement:

The perimeter of a rectangular agricultural test plot is $160\text{ m}$. If the ratio of length to breadth is $5 : 3$, the area of the plot in $\text{m}^2$ is:

Options:

  • (A) $1500$
  • (B) $1200$
  • (C) $1600$
  • (D) $1800$

Answer Key:

A

Step-by-Step Solution & Explanation

Perimeter $2(l + b) = 160 \implies l + b = 80$. With $l : b = 5 : 3$: $8x = 80 \implies x = 10$ Length $l = 50\text{ m}$, breadth $b = 30\text{ m}$. Area $A = l \times b = 50 \times 30 = 1500\text{ m}^2$.
