Question

the length and breadth of a rectangular plot are in ratio 9 ratio 5 if its perimeter is 280 find its area​

Answer 1

Answer:4500

Step-by-step explanation:

Let l=9x and b=5x then perimeter of rectangle = 2(l+b) putting values 2(5x+9x)=280 2×14x=280 x=10 so l=9×10=90 and b=5×10=50 now area=l×b so area=90×50 =4500 I hope it helps.

Answer 2

Answer:

let the length and breadth of the rectangular plot be 9x and 5x

= 9x +5x =14x

= 280 = 20

14x

length of the plot = 9 ×20=180

breadth of the plot= 5 ×20= 100

area of the rectangular plot= length × breadth

=180 × 100= 18000 is the answer
