the length of a rectangle is 4cm less than twice it’s width. the perimeter of the rectangle is 34 cm. what are the dimensions of
the rectangle
1 answer:
Answer:
w=width
l= 2w-4
perimeter of a rectangle = 34
34 = 2(2w-4+w)
34 = 4w-8+2w
34 = 6w-8
6w = 34+8
6w = 42
w = 42/6
width = 7
length = 2w-4
= 2(7)-4
= 14-4
= 10
