Question

80cm rectangle 3:2 given the paremetre is 80 whats the length of the ractangle

Answer 1

Answer:

Answer is 24 cm

Step-by-step explanation:

Let the length of rectangle = 3x

The breadth if rectangle= 2x

we know that,

The perimeter of rectangle = 2(l+b)

2(3x+2x) =80

2×5x = 80

x = 80/10

x=8

Now

the length of reactangle = 24cm

Answer 2

Answer:

24 cm

MARK ME AS BRAINLIEST

Step-by-step explanation:

Given,

Perimeter of rectangle is 80

and ratio of length to breath is 3:2

let the ratio to be 3x,2x

perimeter of rectangle = 2(l+b)

so,

2(3x+2x)= 80cm

2 × 5x = 80( dividing both side by 10)

x= 8çm

length = 3x so 3×8

= 24 cm
