Question

length of rectangle feild is h meters less than 3times it's breath if it perimeter is 72 find area​

Answer 1

Answer:

243 sq.units

Step-by-step explanation:

Perimeter of rectangle=2(l+b)

if length=h metres

then breadth=3h....as length is 3times less than breadth

Perimeter of the rectangle=2(l+b)

72 = 2(h +3h)

72=2(4h)

72=8h

72/8=h

9= h

length = h= 9

breadth = 3h = 27

Area of rectangle = l×b

= 9 ×27

= 243sq.units
