Question

If the ratio of the length to breath of a rectangle be 5:3 and it's pereter is 144 m, find the length of the rectangle

Answer 1

Answer:

Length=45m and Breadth=27m

Step-by-step explanation:

Let the length of rectangle=5x and breadth=3x.

Perimeter=144m

To find out the lenght and breadth we have apply formula perimeter=2*(length+breadth)

144=2*(5x+3x)

144=2*8x

144=16x

x=9

Now, we have the value of x

so,length = 5*9=45m

breadth=3*9=27m
