Question

The area of a rectangular garden is 512 cm. If its length is double of its breadth, what is the perimeter
of the garden?
​

Answer 1

Answer:

let the breadth of garden= (x) m

length of garden= (2x) m

according to question,

area of rectangular garden= 512 m²

x × 2x=512

2x²=512

x²=256

x=√256

x=16 m

length of garden=2×16=32m

breadth of garden=16m

perimeter of garden=length+breadth

=16+32

=48m

Answer 2

Answer:

48 cm

Step-by-step explanation:

let the length-x m

length of the garden- (2x)m

area of rectangular garden- 512 sq.m

2 x - 512 sq. m

2 x square-512 m

x square-256 m

square of 256- 16m

breadth-16

length-16 x 2=32m

so the perimeter

=(16 x 2 )+(32 x 2)=96m
