### What is length of diagonal line in a rectangle 34 feet by 30 feet?

The diagonal line forms two triangles, each with one side 34 feet long and one side 30 feet long. Use Pythagorean Theorem to find the length of the diagonal line which is the hypotenuse of the triangles. a^2 + b^2 = c^2 Where a and b are the sides of the triangle and c is the hypotenuse. (34)^2 + (30)^2 = c^2 1156 + 900 = c^2 2056 = c^2 45.34 = c So, the diagonal line is 45.34 feet.

### Is a diagonal line through a rectangle equal to the vertical and horizontal sides?

No. The diagonal through a rectangle can be computed via the Pythagorean theorem: c2 = a2 + b2 where c is the diagonal length and a and b are the horizontal and vertical lengths of the rectangle.

d = 11.5 inches.

### How long is the diagonal of a rectangle with dimensions 7in by 10in?

You use the pythagorous theorm to calculate the hypotenuse of the triangle, which is the same line as the diagonal. 7(7)+ 10(10)= diagonal x diagonal 149= diagonal x diagonal Diagonal= square root of 149: this approximates to 12.207in Visit quickanswerz.com for more math help/tutoring! Consider a rectangle with dimensions 7 inches by 10 inches. Let ABCD be the rectangle. We need to find the length of the diagonal. We know that the diagonals of a rectangle are same in length. So, it is enough to find the length of the diagonal BD. From the rectangle ABCD, it is clear that the triangle BCD is a right angled triangle. So, we can find the length of the diagonal using the Pythagorean Theorem. BD2 = BC2 + DC2 BD2 = 102 + 72 BD2 = 100 + 49 BD2 = 149 BD = &radic;149 BD = 12.207 So, the length of the diagonal is 12.21 inches. Source: www.icoachmath.com

### How do you trisect a rectangle?

To trisect a rectangle first draw the two diagonals (lines going from the top left corner, to the bottom right and top right to bottom left.) Where those two diagonals intersect is the center of the rectangle. Next, draw a line through the center of the rectangle that is parallel to the top and bottom of the rectangle. this should divide the rectangle into two halves. Next draw the diagonal for the top half of the rectangle (A line from the top left corner, to the middle of the right side.) Where this diagonal intersects with the diagonal of the diagonal of the entire rectangle is 1/3 the length. Repeat the previous step for the bottom half of the rectangle. The line connecting the top intersection, and the bottom intersection is the trisection line.
