*multiply that by 4 for all of the sides*
for the square:
add them together to get 84 :) <3
B. Lines EI and HG are parallel
If the triangles are similar, then the corresponding angles are congruent. Specifically we can get a pair of congruent alternate interior angles, which leads to parallel lines.
100 in square
LSA of square based pyramid = 2×a×l
= 100 in square
Lateral area doesnt include the base
Lateral Area= 1/2 * Perimeter of Base * Slant Height
200 ft^2 = 1/2 * 40 * 10
Triangle sides: 12x10/2. Then multiply by four to get all four sides.
Add together, get 384.
A pyramid with equilateral triangle
the lateral surface area(LSA)=3/2*a*l
A square base pyramid,
sides(a) = 8cm
length(l) = 6cm
lateral surface area(LSA) = ?
LSA = 2al
I submitted an answer but realized it was wrong. My bad
it MIGHT be 145 but im not positive
