Answer:

let the width be 'x' cm long

therefore length =3x cm

A.T.Q

2(3x) + 2x =72

8x=72

therefore x= 9

therefore width =9cm,. length =27cm

hence area = 27×9 = 243cm

Answer:

243cm²

Step-by-step explanation:

let length=x and breadth =3x

2(l+b)=peri of rectangle

substitute the values

2(x+3x)=72

2(4x)=72

8x=72

x=72/8=9

3x=27

area of rectangle=l×b

9×27=243cm²
