Question

Please help what is the are of the triangle!!

Answer 1

Answer: B

Explanation:

the formula for area of a triangle is base times height divided by 2

to get the base do 12.3 x 2 = 24.6

24.6 x 25.6 = 629.76

629.76/2 = 314.88

the answer would be B

(sorry for saying the answer was A at first, i forgot to find the full base)

Answer 2

B. 314.9m

Explanation:

First, let's take a look at the formula of a triangle.

A=
`(1)/(2)`(b * h) ALSO WRITTEN AS- A=
`((b*h))/(2)`.

So, as you can see, there is only half the base provided. To get the other half, just multiply it by 2. You get 24.6m as the base.

The height is provided. It's 25.6m. Plug in your base and height values and slove.

A=
`(24.6m * 25.6m)/(2)`

A=
`(629.76)/(2)`

A= 314.88m

You then round to the nearest tenth.

The final answer is A=314.9m.
