Answer:

84,375 m^2

Step-by-step explanation:

We need to find the surface area of the pyramid. The pyramid can be divided into 4 triangles and one square (the bottom).

Area of a triangle is 1/2*b*h where b is the base of the triangle and h is the height.

Area of a square is length times width.

Total area = $4\times(\frac{1}{2}\times 225 \times 75)+225\times225 = 84375 m^2$

Kobe took $43 to the movie theater if you paid for three to get that each cost de dollars he will have 43 3-D left how much does

siniylev [52]

If each ticket is $9.75, then you multiply $9.75 by how many tickets he's buying. In this case he's buying 3, so it's 9.75x3. The total for that is $29.25. You subtract $28.25 from $43 and that leaves him with $13.75
