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
