Answer:
• lateral area: 36√3 square units
• total surface area: (36 +36√3) square units
Step-by-step explanation:
The area of an equilateral triangle of side length s is given by ...
A = (√3)/4·s^2
Your pyramid has four (4) such faces of side length 6 units, so the total (lateral) area of the triangular faces is ...
LA = √3·(6 units)^2 = 36√3 square units
___
Of course the area of the square base is simply the square of its edge length, so is ...
A = (6 units)^2 = 36 square units
That means the total surface area, the lateral area plus the base area, is ...
(36 +36√3) square units

Answer:
5
Step-by-step explanation:
First, let us simplify the expression on the left
8(4+3) - 21 = 8(7) - 21 = 8(7) - 3(7) = 7(8-3)
Divide this by 7 and you'll get 8-3 = 5
