Question

perimeter of a rectangle is 24and its length and breadth are in the rario 3:5 what is it's length and breadth ?​

Answer 1

Step-by-step explanation:

Ratio of length and breadth of the rectangle is 5 : 3

Let the common multiple be x

So, let the length be 5x and breadth be 3x

Perimeter is 240m

We know that,

Perimeter of a rectangle = 2(length + breadth)

According to the given condition,

2(length + breadth) = Perimeter

∴ 2(5x + 3x) = 240

∴ 2(8x) = 240

∴ 16x = 240

∴ x = 15

∴ Length of the rectangle ➾ 5x

➾ 5 × 15

➾ \boxed{\boxed{\tt{75\:m}}}

75m

∴ Breadth of the rectangle ➾ 3x

➾ 3 × 15

➾ \boxed{\boxed{\tt{45\:m}}}

45m

Area of rectangle = length × breadth

➾ 75m × 45m

➾ \boxed{\boxed{\boxed{\boxed{\tt{3375\:m^2}}}}}

3375m
