Answer:

$LA=162\ in^2$

Step-by-step explanation:

we know that

The lateral surface area of the triangular prism of the figure is equal to

$LA=Ph$

where

P is the perimeter of the triangular base

h is the height of the prism

Find the perimeter of the base P

$P=8+7+12=27\ in$

we have

$h=6\ in$

substitute in the formula of lateral area

$LA=27(6)=162\ in^2$

MARKING BRANLIEST!!

Area of a triangle is = 0.5bh
if the height (h) is 4 less than base (b) then h = b - 4

48 = 0.5(b)(b - 4)
48/0.5 = b² - 4b
96 = b² - 4b
b² - 4b - 96 = 0
(b + 8)(b - 12) = 0

b must be either -8 or 12

since a distance can't be negative that means
the base is 12

Point F is a centroid of the triangle BDE. If AB = 24 cm, what is BE?

Alex17521 [72]

Answer: i know this is way late, but it’s 48

Step-by-step explanation:

Since point A is the separation of BE, both sides of the separation are equivalent, the are congruent. Since AB=24, you add 24+24 to get 48.

(I also just answered this question on homework and got it right, this is just how I did it.)
