Question

length and breadth of a rectangle are in ratio 3:4 , if perimeter is 280m then find area​

Answer 1

Answer:

length = 3x

breadth = 4x

perimeter = 280 m

area = length into breadth =3x into 4x

=2x=3 into 4

2x=12

x=12 / 2

x=pls mark me the brainliest

Answer 2

Answer:

Step-by-step explanation:

let length n breadth be 3x and 4x.

perimeter= 2(*l+b)

280=2( 3x+4x)

280= 24x

280/24=x

11.66=x

now fnd the area by putting the value of x in length n breadth
