1.	The length of a rectangle is I em more than its width and its perimeter is 14 cm. Then the area ofrectangle is
Answer» LET the width be x and LENGTH x +1 perimeter= 2(l+b) 14 = 2(x+x+1) 14/2 = 2x+1 7-1= 2x x= 3 cm then , length= 3+1 = 4 width= 3 area= l × b =4 × 3 = 12cm^2

The length of a rectangle is I em more than its width and its perimeter is 14 cm. Then the area ofrectangle is

Answer»

LET the width be x and LENGTH x +1

perimeter= 2(l+b)

14 = 2(x+x+1)

14/2 = 2x+1

7-1= 2x

x= 3 cm

then , length= 3+1 = 4

width= 3

area= l × b

=4 × 3

= 12cm^2
