The Length Of The Cnhs Math Garden Is 5 M Less Than Twice Its Width Its Perimeter Is 32 Meter What Are Its Dimension class=

Sagot :

Answer:

Length= 9

Width= 7

Step-by-step explanation:

On the given the Length is = 2W - 5

P = 2L + 2W

Given perimeter is 32

32 = {(2)2W - 5} + (2)W

32 = 4W - 10 + 2W

32 + 10 = 4W + 2W

42 = 6W

Divide both sides by 6

7 = W

or

W = 7

L = 2W - 5

L = 2(7) - 5

L = 14 - 5

L = 9

Checking

P = 2L + 2W

32 = 2(9) + 2(7)

32 = 18 + 14

32 = 32
