The length of a rectangle is four times its width. Its perimeter is no greater than 170 cm. Find the greatest possible dimension
s of the rectangle.
1 answer:
Step-by-step explanation:
let the length be =L
the width is 4 × the length
so the width will be 4L
the formular for the perimeter of a rectangle is =2(L +W)
170=2(L +4L)
170=2(5L)
170=10L
17=L
so the width is 4 × the length
17×4
=68
L=17
W=68
