The roof is made up of 2 similar pieces of 2 rectangle shapes.
----------------------------------------------------------------
Area of a rectangle = Length x Width
----------------------------------------------------------------
Area of a rectangle = 50 x 14 = 700 ft²
----------------------------------------------------------------
Area of 2 rectangle pieces:
----------------------------------------------------------------
Area of 2 rectangle pieces = 700 x 2 = 1400 ft²
----------------------------------------------------------------
Find the cost:
----------------------------------------------------------------
1ft² = $2.75
1400 ft² = 2.75 x 1400
1400 ft² = $3850
---------------------------------------------------------------------------------------------
Answer: It will cost $3850 to have the roof replaced. (Answer A)
---------------------------------------------------------------------------------------------
Hence, the sum of the given GP is 16347
<h2>What is a series?</h2>
a series is the cumulative sum of a given sequence of terms. Typically, these terms are real or complex numbers, but much more generality is possible.
<h3>How to solve?</h3>
we can identify from the given geomertric series.
first term = a(say) = 3
geometric factor of progression = r(say) = 4
Sum of the first 7 terms = a(
) ,where n is 7
Sum = 3(
) = 16348-1
= 16347
Hence, the sum of the given GP is 16347.
