● This question says that length of a rectangle is 5 cm and it's breadth is 3 cm then we have to find the ratio of it's perimeter to it's area. So it's cleared that which formulas we have to use here !. Let's solve this question !.

● Length of rectangle = 5 cm

● Breadth of rectangle = 3 cm

● The ratio of it's (rectangle) perimeter to it's area.

● The ratio of it's (rectangle) perimeter to it's area = 16:15

● Formula to find area of rectangle.

● Formula to find perimeter of rectangle.

● Area of rectangle = l × b

● Perimeter of rectangle = 2(l+b)

~ Let us find area of this rectangle first,

★ Length of rectangle = 5 cm

★ Breadth of rectangle = 3 cm

★ Area of rectangle = l × b

Area of rectangle = 5 × 3

Area of rectangle = 15 cm²

~ Let us find perimeter of this rectangle now,

★ Length of rectangle = 5 cm

★ Breadth of rectangle = 3 cm

★ Perimeter of rectangle = 2(l+b)

Perimeter of rectangle = 2(5+3)

Perimeter of rectangle = 2(8)

Perimeter of rectangle = 2 × 8

Perimeter of rectangle = 16 cm

~ Not at last let us find the ratio of it's (rectangle) perimeter to it's area

★ Perimeter of rectangle = 16 cm

★ Area of rectangle = 15 cm²

So, perimeter : area

Henceforth, 16:15
