Question

A rectangular garden has a length three times it's breadth and it's breadth is 120 m .Find the area and perimeter of the rectangular garden

Answer 1

Answer:

area=-43200 m2

perimeter=960 m

Step-by-step explanation:

Let length of rectangle=lcm

breadth of rectangle= bcm

Given length is 3 times its breadth

i.e. l= 3×b

Perimeter of the rectangle= 120 cm

i.e.2×( l+ b)=120

2×(3×b+ b)=120

2×(4×b)=120

8×b=120

b= 15 cm

Answer 2

Answer:

Given , Breadth = 120m

Length = 120 X 3 = 360 m

Perimeter = 2(l + b)

= 2( 360 + 120 )

= 2 X 480

= 960 m

Answer

Area = l X b

= 360 X 120

=43200 m ^2
