Question

The length of  a rectangle is four times its breadth. If the
perimeter of the rectangle is 280 metres, find its area.

Answer 1

Answer:

3136 sq. m

Step-by-step explanation:

Let the breadth of the rectangle be 'x'.

then its length will be 4x.

According to question,

2(4x+x) = 280

2(5x)= 280

10x = 280

x= 28.

Breadth =28.

length=4 × 28

= 112

Now area = l×b

= 112 ×28

=3136 sq. m

Answer 2

3136 meter square

Step-by-step explanation:

let the breadth of rectangle be 'b'

therefore length will be 4b (4 times of breadth)

perimeter of rectangle = 2(l+b)

280=2(4b+b)

b=28

l= 28x4=112

area of rectangle = lxb

                             =28x112

                               =3136
