Question

find the perimeter if area of rectangle with breath 17cm is 340sq.cm

Answer 1

We know that area of a rectangle is length x breadth
Thus putting the value of breadth and area we get,
17 x length = 340
Length = 340/17
Length = 20 cm

Now that we have both length and breadth, we know that,
Perimeter of rectangle = 2(length + breadth )
Perimeter= 2(17+20)
Perimeter = 2 x 37 = 74 cm
