Question

divide rs 480 in the ratio 2:5 between a and b​

Answer 1

Let the length and breadth of rectangle be 5x and 3x respectively.

Perimeter of rectangle = 2( l+b )

➡ 480 = 2 ( 5x + 3x )

➡ 480 = 2 ( 8x )

➡ 16x = 480

➡ x = 480/16

➡ x = 30.

So,

Length = 5x = 5(30) = 150

Breadth = 3x = 3(30) = 90

Now,

Area of rectangle = l × b

➡ 150 × 90

➡ 13500 unit²

Required answer is 13500 unit².
