Question

find the length of rectangle area is 320 cm and breadth is 60 and length find out
​

Answer 1

Hey Friend,

Let x be the common factor

Ratio=3x:5x

Perimeter= 2(l+b)

320= 2(3x+5x)

320/2= 8x

8x= 160

x= 20

Therefore,

Length=3x=3*20=60

Breadth=5x=5*20=100

Hope it helps.... :)

Answer 2

Let the length be x.

Given,

breadth = 60cm

area = 320cm square

Area of rectangle = length × breadth

320 = x × 60

320 = 60x

320/60 = x

5.333 = x

Thus, the length of the rectangle is 5.3cm(approx).
