Answer: The perimeter of the largest triangle = 117 units.
Step-by-step explanation:
Sides of smaller triangle = 10,20 and 15 units
Longest side = 20 units
Longest side of larger triangle = 52 units
Sides of two similar triangles are proportional.
Let k be proportionality constant.
![k=\dfrac{\text{Length in larger triangle}}{\text{Length in smaller triangle}}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B%5Ctext%7BLength%20in%20larger%20triangle%7D%7D%7B%5Ctext%7BLength%20in%20smaller%20triangle%7D%7D)
![k=\dfrac{52}{20}\\\\\Rightarrow\ k=\dfrac{13}{5}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B52%7D%7B20%7D%5C%5C%5C%5C%5CRightarrow%5C%20k%3D%5Cdfrac%7B13%7D%7B5%7D)
Length of other two sides,
![10\times\dfrac{13}{5}, 15\times\dfrac{13}{5}\ i.e.\ 26\text{ units}, 39\text{ units.}](https://tex.z-dn.net/?f=10%5Ctimes%5Cdfrac%7B13%7D%7B5%7D%2C%2015%5Ctimes%5Cdfrac%7B13%7D%7B5%7D%5C%20i.e.%5C%2026%5Ctext%7B%20units%7D%2C%2039%5Ctext%7B%20units.%7D)
So sides of larger triangle = 52 units, 26 units , 39 units
Perimeter of largest triangle = 52 +26+39 = 117 units
Hence, the perimeter of the largest triangle = 117 units.
Solution:
Total number of Days that Pooja's plant survived= 2 + 98 = 100 Days=(t)
Longest Height obtained by plant = 30 cm= h
As the two , i.e number of Days lived by plant and it's longest height obtained are directly proportional.
We will solve it by unitary method.
100 Days = 30 cm
1 cm = Days
If height of the plant is h cm ,and amount of time taken is t days, then
h(t) cm = ,for t=0,1,2,3,4,5,6....we get different values of h.
The route to an ancient pyramid is 79 miles long; if 20 miles is travelled each day for 3 days, the distance travelled in the fourth day would be 19 miles.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let the distance travelled in the first day be 20 miles. If the same time was travelled for 3 days, hence:
3(20) + x = 79
x = 19 miles
The route to an ancient pyramid is 79 miles long; if 20 miles is travelled each day for 3 days, the distance travelled in the fourth day would be 19 miles.
