Question

The ratio of the length of a rectangle
to its breadth is 5:2. If its area is 1690
cm?, find the perimeter of the
rectangle.​

Answer 1

Answer:

First to take out length and breadth by formula of area of rectangle then to find out perimeter.

Answer 2

Answer:

182cm

Step-by-step explanation:

let the length be 5x and breadth be 2x

Area = length×breadth

1690 = 10(x^2)

13 = x

length = 5x = 65cm

breadth = 2x = 26cm

Perimeter = 2(length + breadth) = 2(65+26) = 182cm
