Question

The perimeter of rectangle is 160 cm. If the breadth of the rectangle is 30 cm, find its length. Also find the area
of the rectangle,​

Answer 1

Step-by-step explanation:

Perimeter= 160cm

breadth= 30cm

length=?

since,

perimeter of rectangle= 2( l+ b)

therefore,

160= 2( l+ 30)

160/2= l+ 30

80= l+ 30

or,

l= 80-30

= 50cm

Now,

Area of rectangle= length*breadth

=50*30

= 1500cm²
