Question

perimeter of rectangular sheet is 100 centimetres. length is 35 centimetre find its breadth also find area

Answer 1

Perimeter of rectangle = 2( length + breadth)

Given perimeter = 100 cm
Let the breadth be "b"

2 ( 35 + b) = 100
35 + b = 50
b = 15 cm

Area = l x b = 525 cm²

So, breadth = 15 cm
Area = 525 cm²

Hope This Helps You!

Answer 2

Hi Friend ,
Length of the rectangle = 35 cm
Perimeter of rectangle = 100 cm
2(l+b) = 100 cm
2(35+b) = 100 cm
70 cm + 2b = 100 cm
2 b = 100-70
2b = 30 cm
b = 30/2
b = 15 cm

Area of rectangle = l× b
Area = 35× 15 cm sq.
Area = 525 cm sq.
