Question

1) The length of rectangle is thrice as long as width. Find the length if the perimeter is
160cm.​

Answer 1

Step-by-step explanation:

Let the width of rectangle b x centimetre

then the length of rectangle = 3 x

perimeter of rectangle is equals to 2 into l + b

we know that the perimeter is 160 cm then 160 is equal to to 2 into X + 3 x

now 160 equals to 2 into X + 3 x

160 equals to 2 into 4x

160 equals to 8 x

160 by 8 is equals to X

20 is equals to X
