183.875 or 183.9 km
Step-by-step explanation:
You would start out by distributing the 4 and 2. then solve.
I got 22.5
tell me if i got it wrong or right
If the Earth were a flat surface, then 9 miles east and 12 miles north would be
the basis of a right triangle, and the straight-line route would be the hypotenuse.
We could use the Pythagorean Theorem to find the straight-line distance.
A² + B² = C²
C² = (9)² + (12)²
C² = 81 + 144
C² = 225
C = √225 = <u>15 miles</u>
That's Choice-'H'.
Answer:
area of the BCD triangle=1/2×10×9
=45
area of the ABD triangle=1/2×10×3
=15
Total area=45+15
=60 square centimetres
