Answer:
The base and the height of the triangle are 15 cm and 10 cm respectively.
Step-by-step explanation:
Given:
The ratio of the base (b) and height (h) = 3 : 2
Area of the triangle = 75 cm²
To find out:
The value of the base and height.
Solution:
Let 'x' be the ratio
Then the ratio of the base = 3x
The ratio of the height = 2x
The formula to find the area (A) of the triangle is given as,
Now substitute the values to find 'x'. Therefore,
⇒
= 25
x = √25
x = 5
Hence, base = 3 × 5 = 15 cm and height = 2 × 5 = 10 cm.
