The length of a rectangle is 4 centimeters more than twice its width. If the perimeter of the rectangle is 86 centimeters, find
the dimensions of the rectangle
1 answer:
width = 13
length = 30
p=2l + 2w
86 = 2(2w+4) + 2w
86 = 4w + 8 + 2w
86= 6w + 8
78 = 6w
13 = w
86 = 2l + 2(13)
86 = 2l + 26
60 = 2l
30 = l
check your work.
l is 4 centimeters more than twice w
twice w = 26
plus 4 = 30

Step-by-step explanation:
use pythagorean theorem
a² + b² = c²
a² + 3² = 7²
a² + 9 = 49

a = 6.324555320336759
Rounded
a = 6.3
