Question

the area of a rectangle is 102 sqcm. if its length is 17 cm ,what is its perimeter?​

Answer 1

Step-by-step explanation:

area of a rectangle = lb

102=17b

102/17=b

b = 6

perimeter of a rectangle = 2(l+b)

2(17+6)

2(23)

46

Answer 2

Answer:46 cm

Step-by-step explanation:

Since area of a rectangle= LENGTH*BREADTH

Therefore,

102=lenght*breadth -(1)

Also given is length=17cm

(Putting value of lenght in equation1)

102=17*breadth

Therefore,

102/17=breadth

Breadth=6cm

Now, perimeter of a rectangle is

2(length+breadth)

Putting values of length and breadth

Perimeter=2(17+6)

Perimeter=2(23)

Perimeter=46 cm
