The length of a rectangle is five times its width. if the area of the rectangle is 245 meters squared, find its perimeter

Your answer is 84 meters.

We can call the width x, and thus the length 5x, and then we can say that 5x × x = 245, which simplifies to 5x² = 245, and then we can solve:

5x² = 245

÷ 5

x² = 49

√

x = 7

Now that we know what x is, we can find the perimeter by using it as the width, and then multiplying it by 5 to find its length. This gives us:

(7 × 2) + (5 × 7 × 2) = 14 + (35 × 2) = 14 + 70 = 84

So your answer is 84 meters.

I hope this helps!

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
