Question

The length of a rectanglesar field
is twice its breath. If the perimeter
of the field is 45 meless, find the
length and breadth of the field.​

Answer 1

Answer:

L = 15 M , B = 7.5 M

Step-by-step explanation:

2(l+b)=45 l=2b

2(3b)=45

6b=45

b=45÷6

b=7.5m

l = 15m

Answer 2

Ste

p-by-step explanation:

let, breath =x

length =2x

perimeter =45m

perimeter of a rectangle =2 (l+b)

=2 (x+2x)

= 2 (3x)

6x=45

x=45/6m

2x=15m

hence length =15m

breath= 45/6m
