Question

The length and breath of a rectangular field are in the ratio 5 : 3. If it's perimeter is 128 m, find the dimensions​

Answer 1

Answer:8

Step-by-step explanation:

Given perimeter=128m

Ratio=5:3

Let length of field be 5x and breadth be 3x

2(5x+3x)=128

8x=64

X=8

Answer 2

Answer:

Step-by-step explanation:

length = 5x

breadth = 3x

perimeter = 2*(5x+3x) = 128cm

therefore, 8x = 128/2cm

or, x = 64/8cm

or, x = 8cm

length = 5x = 5*8 = 40cm

breadth = 3x = 3*8 = 24cm
