Question

abcd is a rectangle . find the length od the diagona.
ac=2x-3
bd=x+5

Answer 1

Is it 0D diagonal or Of the diagonal?

Answer 2

of the diagonal

Answer 3

diagonals of a rectangle are equal ==> ac = bd
2x-3 = x+5
2x - x = 5 + 3
x = 8
so ac = 2(8) - 3 = 16 - 3 = 13
bd = x+5 = 8 + 5 = 13

Answer 4

that is wronq

Answer 5

Sqrt[(2x-3)^2+(x+5)^2]

Answer 6

then you have put the question wrong

make the rectangle and you will see that ac and bd are the diagonals.......

Answer 7

while naming the rectangle, you have to name either clockwise or anticlockwise..
so and c will be always in opposite corners and the line joining them will be the diagonal....
similarly for ac....
