Question

The length of rectangle in three times its width and its perimeter is 56 the length is
a) 7m
b) 14m
c) 21 m
d)28m​

Answer 1

Answer:

14m=width

Step-by-step explanation:

Answer 2

Let,

• Width = x
• Length = 3x

Perimeter of Rectangle = 2( l + w )

=> 56 = 2( 3x + x)

=> 56 = 6x + 2x

=> 56 = 8x

=> 8x = 56

=> x = 56/8

=> x = 7

Therefore,

• Width = x = 7m
• Length = 3x = 3×7 = 21m

Hence, Length is 21cm and option c is correct.
