Lengths of corresponding sides of similar polygons are in proportion.
That means that 2 is to 3 as 7 is to x where x is the length of the side of the other
triangle.
2/3= 7/x
2x = 21
x = 21/2 = 10 1/2
Answer: b) 10 1/2
Answer:
base = 15 units
Step-by-step explanation:
We are given area of a triangle = 52.5 sq. units
Height is given as 7 and we have to find the base.
Using formula for area of triangle:
Area of triangle = ![\frac{base*height}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bbase%2Aheight%7D%7B2%7D)
![52.5 = \frac{base*height}{2}](https://tex.z-dn.net/?f=52.5%20%3D%20%5Cfrac%7Bbase%2Aheight%7D%7B2%7D)
![52.5 = \frac{base*7}{2}](https://tex.z-dn.net/?f=52.5%20%3D%20%5Cfrac%7Bbase%2A7%7D%7B2%7D)
52.5 * 2 = base × 7
105 = base × 7
base = 15
