The area of a triangle block is 64 square inches if the base of the triangle is twice the high how long are they base and the height of the triangle

The height is 8 and the base is 16

Step-by-step explanation:

the area of a triangle is bh, where b is the length of the base, and h is the length of the height.

We are given that the base is twice the height, so b=2h. If we substitute b for 2h in our equation, we get that the area of the triangle is (2h)(h), which equals h^2.

Therefore, the area of this triangle is h^2. We are given that the area is 64, so h^2=64. The only positive value for h is 8, so h=8.

Since b=2h, b=2*8=16, so the height is 8 and the base is 16

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
