The key word here is ‘perpendicular’. Since they say that the cross section is perpendicular to the rectangular base, the cross section will still be a rectangle, just smaller, as long as it does not pass through the top vertex.

Therefore, the answer is (b) a rectangle.

Just a side note: IF the cross section is perpendicular to the base and it DOES pass through the top vertex, then it will have no shape at all, since it will just be a single point.

The effective rate of interest will be 9.10 %.

<h3>What is compound interest?</h3>

Compound interest is applicable when there will be a change in principle amount after the given time period.

Let's say you have given 100 for two years with a 10% rate of interest annually than for the second-year principle amount will become 110 instant of 100.

Given for simple interest

Principle amount = $650

Rate of interest = 12%

Time period = 7 months.

Interest= PRT/100

Interest= 650× 12 × 7/100 = 546

So final amount = 650 + 546 = $1196

By compound interest

1196 = 650 $[1 + R/100]^{7}$
