A rectangle has an area of 192 square inches. Find it’s length and width if the length is 3 times the width
Ber [7]

Answer: Width = 9 inches

Length = 12 inches

Step-by-step explanation: A = (w+3)(w)

A = w2 + 3w = 108

w2 + 3y - 108 = 0

This is the factor of the problem: (w - 9) (w + 12) = 0

This equals to w + 12 = 0

w = -12

Then the final answer would be Width = 9 inches

Length = 12 inches.

Hope this helps!

I am joyous to assist anytime!

Juliette [100K]

Answer:

93 miles

Step-by-step explanation:

Use the distance formula:

d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}

Plug in the values:

d = \sqrt{(121 - 57)^2 + (79 - 11)^2}

d = \sqrt{4096 + 4624}

d = \sqrt{8720}

d = 93.4

= 93 miles
