Answer: the perimeter of a rectangle sheet is 90cm .if the length is 25 cm, find its breadth also the area​

Let length = l cm

breadth = b cm

l =25 cm

1. P=90 cm

2(25+b)=90

25+b=90/2

25+b=45

b=45-25

=20cm

2. A=l*b

    =20cm * 25cm

   =500cm²

therefore ,

the breadth of the rectangle sheet is = 20cm

the area of the rectangle sheet is= 500cm²
