Area and Perimeter
To find the area of a square, you multiply the length times the width. If you know the area of the square, you find its square root to find the length of each side. The square root of 121 is 11. Now take the square root of 289. Please post your answer and we'll check it.

Okay, this one you really really should plot out the coordinates. It will give you an approximate orientation of the line. If plotted it out and realized that ST is a diagonal segment with a POSITIVE slope (meaning it goes up from left to right, that let you know that the y ...

you gave B = 43 C = 107 B = 14 What does that mean, are they angles or lengths of sides. Please be more specific. knowing these kind of questions, I will assume that 14 units is the length of the side opposite the 43º angle. then the third angle is 30º and by the Sine Law c/...

tan x= (opposite side length)/(adjacent perendicular side length) = sin x/cos x sin x = (opposite side length)/(hypotenuse) = x - x^3/3! + x^5/5! -... (if x is in radians) cos x = (adjacent perpendicular side length)/(hypotenuse) = 1 - x^2/2! + x^4/4! - ... (if x is in radians...

2 questions. for math.
i have another question about squares? the question is, a square has an area of 81 square feet. what is the length of each side? i don't really know because it doesn't show the width so i can't do w.l ?? what do i do?

Two adjacent corners of a square have charges q1 = +1.5 x 10-9 C and q2 = +4.0 x 10-9 C. The length of a side of the square L = 0.25 m. Find the EPE of a charge q3= -6.0 x 10-9 C placed at the 2 remaining corners.

Since x^2 + 18 x + 81 = (x+9)^2, the cage must still be square and increased in length of each side by 9 meters. That answers (1) and (2). (3) If the old area was 25 m^2, the old side length a was sqrt 25 = 5 m. Now it is 5 + 9 = 14 m

Choose a rectangle with arbitrary side lengths a and b. The proof will be easier if you locate one corner at the origin (0,0). Let a be the length of the side on the x axis Derive equations for the two diagonals. One equation will be y1 = (b/a)x The other will be y2 = b -(b/a)...

according to the smithsonian institute, many of the original stones were removed and or eroded. The length of one side of the square base originally measured 207 ft. less than twice the height. The original volume of the great pyramid was 91,394,008 ft.cubed. Use the formula ...

I have a question: My textbook says "The surface of a right prism is 224 sq. feet, and the length of a side of the square base is one-third the height. What are the dimensions of the prism?" How do I find out the dimensions when I don't know the height or the length of the ...

Algebra I need the formula not the answer
If the sides of a square are lengthened by 8cm the area becomes 169^2. Find the length of a side of the original square. I am getting 34.25cm

Algebra I need the formula not the answer
The square root of 169 is 13, which is the lengthened measure of each side. Subtract 8 from 13 to find the original length of each side.
