The proportion is simply a matter stating the ratios as fractions, setting two fractions equal each other and cross multiplying.
For example:
2/x=3/9.
You need to cross multiply in order to get your answer. so 9(2)=x(3)
18=3x
6=x.
Thats how you solve a proportion.
Hope this helped :)
Have a great day
Answer:
equilateral triangle is GHK,
the 2 isosceles triangles is GKJ and KHJ
scalene triangle is GHJ
Step-by-step explanation:
If the ratio of the dimensions is 4:7 and the shorter dimension is 10ft, we know that the 10ft corresponds to the 4 in this scenario. We can set up the equation as follows:
You have to multiply by 2.5 to get from 4 to 10. And since we want to make sure we are maintaining the ratio, we have to multiply the denominator, 7, by 2.5 as well.
This means your shorter side has a length of 10ft and your longer side has a length of 17.5ft.
AREA
The formula for the area of a rectangle is:
So we can plug our dimensions into the formula:
So 175 is our area. But we can't forget about units! Since this is area and we multiplied our units together, our units would be squared. That means our answer is <u>175 square feet</u>.
PERIMETER
The formula for the perimeter of a rectangle is:
We can plug our dimensions into the formula:
So 55 is our perimeter. Of course, we can't forget about our units. Because this is perimeter, we only added our units together, so they don't change. That means our answer is <u>55 feet</u>.
