Answer:
The second/below one is where point G in an orthocenter
Step-by-step explanation:
The area for the perimeter of a rectangle is:
<em>P = 2l + 2w</em>
In this problem, we are given that
P = 155 and
l = 45.5. To solve for area, we must find w. To do this, plug in the given info and isolate the w like so:

Now we know
w = 32. Knowing all the necessary info, we can use the area formula, <em>A=lw</em>, to solve for A.

The area is
1,456 sq ft. Hope this helps!
Answer:
the lateral area of the regular prism is 30 cm².
Step-by-step explanation:
Given;
the base of the regular prism, b 4cm
height of the prism, h = 2.5 cm
The lateral area of the regular prism is calculated as the product of the base perimeter and height of the prism.
L.A = P x h
where;
P is the perimeter of the base = 3 x 4cm (equilateral triangle has equal sides)
P = 12 cm
L.A = 12 cm x 2.5 cm
L.A = 30 cm²
Therefore, the lateral area of the regular prism is 30 cm².
