Find the surface area of each right regular pyramid. a pentagonal pyramid with base sides 1.5 meters, base area 3.9 m2, and slant height 4 meters

The answer is 18.9, i think, because there is a formula for finding the total surface area of such pyramids, but i used the simpler way of finding all the separate areas of each face using this information:

since the base area is 3.9 m2, we could just add that to the total at the end.

since the base edge is 1.5 m and the height is 4m, we could find the area of the face by doing (1.5 times 4)/2 which would give us 3m2. 

Since there are 5 faces(pentagonal), we would multiply 3 times 5, and would get 15m total for all the triangle faces.

so to get the total surface area, you would add 15 + 3.9 (which was the base area) and get 18.9m2

;);) hope this helps

Hello!

the answer is:

the answer is:

why?

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
