So the correct answer is A, Quantity A is greater. And multiplying a value by $0.99$ decreases its magnitude, so the area of rectangle $B$ is slightly smaller than the area of rectangle $A$.
Looks like the area of rectangle $B$ is the same as the area of rectangle $A$ EXCEPT that it is multiplied by $0.99$. In terms of the dimensions of rectangle A, the area of rectangle A is:Īnd the area of rectangle $B$, expressed in terms of the dimensions of rectangle $A$, is: $\Area_B$ Perfect! Looks like we have everything we need to calculate the areas of both rectangles in terms of the dimensions of rectangle $A$, so let’s do that right now. We need to translate this into a math equation, but first let’s remind ourselves of the formula for calculating a new value from a percentage change. Next, we know that the length of rectangle $B$ is $10$ percent less than the length of rectangle $A$. We want to compare the areas of two rectangles, so let’s start by recalling the formula for the area of a rectangle We want to compare the areas of rectangles $A$ and $B$.The width of rectangle $B$ is $10$ percent more than the width of rectangle $A$.The length of rectangle $B$ is $10$ percent less than the length of rectangle $A$.Let’s carefully read through the question and make a list of the things that we know. Let’s keep what we’ve learned about this skill at the tip of our minds as we approach this question. Since we’ll be comparing areas of rectangles, we should expect to use what we’ve learned about Quadrilaterals here. Pay attention to any words that sound math-specific and anything special about what the numbers look like, and mark them on our paper. Let’s search the problem for clues as to what it will be testing, as this will help shift our minds to think about what type of math knowledge we’ll use to solve this question. Those questions testing our knowledge of Quadrilaterals can be kind of tricky, but never fear, PrepScholar has got your back! Survey the Question Buuuut then you had some questions about the quant section-specifically question 6 of the second Quantitative section of Practice Test 1. So, you were trying to be a good test taker and practice for the GRE with PowerPrep online. The relationship cannot be determined from the information given.The length of rectangle $B$ is $10$ percent less than the length of rectangle $A$, and the width of rectangle $B$ is $10$ percent greater than the width of rectangle $A$.
