What is the total area, in square units, of the four triangular faces of a right, square-based pyramid that has base edges measuring six units and lateral edges measuring five units?

(PLease send help quick thank you so much)

The total area of the four triangles is 48 square units

Step-by-step explanation:

we know that

The lateral area of the square pyramid is equal to the area of the four triangular faces

so

where

Find the height of the triangular faces

Note: The height of the four triangles is the same because is a right square pyramid

Applying the Pythagorean Theorem

Find the lateral area

substitute the given values

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
