a rectangular patio has a perimeter of 60 feet. if the length of the patio is 3 feet less than twice the width, find the dimensi
Juli2301 [7.4K]
P = 2(L + W)
P = 60
L = 2W - 3

60 = 2(2W - 3 + W)
60 = 2(3W - 3)
60 = 6W - 6
60 + 6 = 6W
66 = 6W
66/6 = W
11 = W <=== the width is 11 ft

L = 2W - 3
L = 2(11) - 3
L = 22 - 3
L = 19 <=== the length is 19 ft

The proportion between the hypotenuse of a right triangle and one of its legs is 13 12 , and the other leg is 15 cm long. Find t
Contact [7]

Answer:

Perimeter = 90

Step-by-step explanation:

Let c = hypotenuse, 15 = b, and a = other leg

Given: c/a = 13/12, so a = 12c/13.

c^2 = b^2+a^2

Using Pythagorean Theorem: c^2 = 225 + 144c^2/169.

 

169c^2 = 169(225) + 144c^2

25c^2 = 169(225)

5c = 13(15)

c = 13(3) = 39.

and a = 12*39/13 = 12*3 = 36

You now can compute all three sides, and

thus obtain perimeter = 36+39+15 = 90.
