Question

there is a rectangle plot whose length is 16cm and area is is 320 CM square find its breadth and perimeter?​

Answer 1

Length = 16 cm

Area = 320 cm²

Length × Breadth = Area

16 cm × Breadth = 320 cm²

Breadth = 20 cm

Perimeter = 2(16 + 20) = 2 × 36 = 72 cm

Answer 2

GIVEN:

Lenght of rectangle is 16cm

Area of rectangle is 320 cm

Find:

Breadth of Rectangle

Area of Rectangle = Lenght ( l ) × breadth ( b )

320 = 16 × b

b = 320 / 16

b ( breadth ) = 20 cm

Breadth of rectangle is 20 cm

now finding perimeter of rectangle .

Perimeter of rectangle = 2 ( l + b )

Perimeter of rectangle = 2 ( 16 + 20 )

Perimeter of rectangle = 2 ( 36)

Perimeter of rectangle = 2 × 36

Perimeter of rectangle = 72 cm

Final answer:

Breadth ( b ) of rectangle = 16 cm

Perimeter of rectangle = 72 cm .
