Answer 2

Answer:

ans 1 - 7 cm

ans 2 - 5 cm

Step-by-step explanation:

ans 10 - Width of rectangle = 6cm

length of rectangle = x cm

perimeter = 2( l+b )

=> 26 = 2 (x + 6)

=> 26 = 2x + 12

=> 26 - 12 = 2x

=> 14 = 2x

=> 7 = 5

thus the length is 7 cm

ans 11- length of rectangle = 6cm

breadth of rectangle = x cm

perimeter = 2( l+b )

=> 22 = 2 (6 + x )

=> 22 = 12 + 2x

=> 22 - 12 = 2x

=> 10 = 2x

=> x = 5

thus the breadth is 5 cm
