Question

The area of a triangle is equal to the area of a rectangle whose length and breadth are 20 cm and 15 cm respectively. Calculated the altitude of the triangle if its base measures 30 cm.​

Answer 1

Answer:

The height of the triangle is 20 cm.

Step-by-step explanation:

Length of rectangle = 20 cm

Breadth of rectangle = 15 cm

Area of rectangle = $Length \times$

$= 20 \times 1520×15$

$= 300 cm^2300cm$

Area of triangle = $\frac{1}{2} \times Base \times Height$

Since we are given that the base of the given triangle is 30 cm

So, Area of triangle = $\frac{1}{2} \times 30 \times$

We are also given that The area of triangle is equal to the area of rectangle

So, 300$=\frac{1}{2} \times 30 \times$

$\frac{600}{30}= Height$

Hence the height of the triangle is 20 cm.
