Question

the perimeter of rectangle is 60 m it's length is double its breath of the rectangle
​

Answer 1

Answer:

length=20 m

breadth=10m

Step-by-step explanation:

Let breadth be x

Length=2x

We know perimeter=2(length+breadth)

By condition,

2(2x+x)=60

2*3x=60

6x=60

x=10

Value of length=20 m

Value of breadth=10m

Answer 2

Answer:

$\sf \large \implies \: given : \\ \\ \sf \bullet \: perimeter \: of \: rectangle \: = 60 \: cm \\ \sf \bullet \: length \: = 2x \: \\ \sf \bullet \: breadth \: = x \\ \\ \sf \large \: solution \: \\ \sf { \boxed{ \underline{ \red{per. \: of \: rect. \: = 2 \times (length + breadth)}}}} \\ \\ \sf \bullet \: 60 \: m \: = 2(2x + x) \\ \\ \sf \bullet \: 60m \: = 2(3x) \\ \\ \sf \bullet \: 60m \: = 6x \: \\ \\ \sf \bullet \: x \: = \frac{60}{6} m \: \\ \\ \sf \bullet \: { \underline{ \boxed{ \green{10 \: m \: }}}} \\ \\ \\ \sf \large \implies \: now \: \\ \\ \rm \bullet \: breadth \: = x = 10 \: m \\ \\ \rm \bullet \: length \: = 2x = 2 \times10 = 20m \: \\ \\ \\ \therefore \large { \boxed{ \boxed{ \underline{ \underline \blue{length = 20m \: and \: breadth = 10m}}}}}$
