Question

If the length and breadth of a rectangle are in the ratio 2:1 and length is 98cm, then what is the breadth? Also find the area of the rectangle​

Answer 1

Answer:

Step-by-step explanation:

let the length of rectangle = 2x...…(1)

and breadth = 1x

length = 98cm...… (given) ….(2)

so, from (1) and (2)

2x = 98

x= 98/2 = 49cm

breadth of rectangle =x = 49cm

area of rectangle = l x b

= 98 x 49 square cm

= 4802 square cm

Answer 2

$let \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ the \: length \: of \: rectangle \: = \: 2x \\ the \: breadth \: of \: rectangle = x \\ given \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ length \: of \: rectangle \: (2x)= 98cm \\ breadth \: of \: rectangle$

$2x = 98cm$

$x = \frac{98cm}{2}$

$x = 49cm$

$breadth = 49cm$

$area \: of \: rectangle = l \times b$

$area \: of \: rectangle = 98cm \times 49cm$

$area \: of \: rectangle = 4802 {cm}^{2}$
