Question

5. The perimeter of a rectangular park is 1440 m. Its
breadth is 50% of its length. Find the area of the
park?​

Answer 1

Answer:

Area of rectangular park is 1,15,200 m².

Step-by-step explanation:

Given,

Perimeter of rectangular park=1440 m

Let, length be x.

Then, breadth =x × 50/100 = x/2

Perimeter of rectangular park= 2(l+b)

1440 m = 2( x +x/2)

1440 m = 2x + x

1440 m = 3x

1440/3 m = x

480 m. = x

So, Length = x = 480 m

Breadth = x × 50/100 = 480 × 50/100

= 240 m

Now,Area of rectangular park = l×b

= 480 ×240m

= 115200 m²
