Question

abcd is rect aoc is seg bc 12 cd 9 oa=?

Answer 1

Answer:

7.5 units

Step-by-step explanation:

ABCD rectangle.

BC=12units

CD = 9 units

BCD is right triangle.

SO, BD=√(BC²+CD²) = √(144+81) = √225 =15units.

IN A RECTANGLE, DIAGONALS ARE EQUAL.

AC = BD⇒AC= 15units.

Usually O is midpoint of line segment. So, AO=1/2AC=1/2×15=7.5 units.
