canveet 180cmto metersFind the perimeter of the rectangle with diametion 1.8 m and 1.5 m Express the Answers in meters​

Answer 1

Answer:

ANSWER EXPLANATION: There are two ways to solve this question. The faster way is to multiply each side of the given equation by ax−2 (so you can get rid of the fraction). When you multiply each side by ax−2, you should have:

24x2+25x−47=(−8x−3)(ax−2)−53

You should then multiply (−8x−3) and (ax−2) using FOIL.

24x2+25x−47=−8ax2−3ax+16x+6−53

Then, reduce on the right side of the equation

24x2+25x−47=−8ax2−3ax+16x−47

Since the coefficients of the x2-term have to be equal on both sides of the equation, −8a=24, or a=−3.

The other option which is longer and more tedious is to attempt to plug in all of the answer choices for a and see which answer choice makes both sides of the equation equal. Again, this is the longer option, and

Answer 2

Answer:

180cm=1.8m

Step-by-step explanation:

length(l)=1.8m

Breadth(b)=1.5m

now,

Perimeter=2(l+b)

               =2(1.8+1.5)m

               =2x3.3m

               =6.6m
