Question

the length and breadth of the rectangular field are in the ratio 5 ratio 3 if its perimeter is 128 metre find the dimension of the of the field​

Answer 1

Answer:

perimeter = 128

Step-by-step explanation:

according to formula of perimeter

p = 2(l+b)

p/2 = l+b

128/2 =l+b

64 = ratio 5+3

then one unit of it = 64/8

= 8

the length = 5×8= 40

the breadth = 3×8 = 24

Answer 2

Step-by-step explanation:

l:b= 5:3

l=5x b=3x

2(l+b)= 128

2(5x +3x)= 128m

2(8x) =128

16x=128

x= 8

l=5x =5(8)=40m

b=3x=3(8)=24m
