Question 145
The perimeter of a rectangular field is 240 metre. The ratio between the length and breadth of the field is 8:7. Find the area of the field.
Solution
Let the length and breadth of the rectangular field be $$8x$$ m and $$7x$$ m respectively.
Perimeter = $$2 (8x + 7x) = 240$$
=> $$15x = \frac{240}{2} = 120$$
=> $$x = \frac{120}{15} = 8$$
$$\therefore$$ Area of field = $$8x \times 7x = 56 x^2$$
= $$56 \times (8)^2 = 3584 m^2$$
