The area of a square picture frame is 55 square inches. Find the length of one side of the frame. Explain to the nearest whole inch.

Given:

The area of a square picture frame is 55 square inches.

To find:

The length of one side of the frame.

Solution:

Let the length of one side of the frame is x inches.

Area of square is

where a is side length.

Area of frame is

Taking square root on both sides.

, so . Since 55 is closer to 49, therefore, is closer to 7.

Therefore, the length of one side of the frame is 7 inches.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

answer: i think one of the answer is $150 and $300?
