Help me out ASAP please. I’m stumped on this one !!

240 in²

Step-by-step explanation:

The net is composed of 3 rectangles and 2 congruent triangles

Calculating the area of the 3 rectangles

A = (5 × 12) + (8 × 12) + (5 × 12) = 60 + 96 + 60 = 216 in²

Calculating the area of the 2 congruent triangles

A = 2 × bh ( b is the base anh h the perpendicular height

Here b = 8 and h = 3, thus

A = bh = 8 × 3 = 24 in²

Total area = 216 + 24 = 240 in²

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
