Brian wants a triangular pennant made of cloth.The base of the pennant is 20cm and its height is 30cm. What is the area of the cloth?​

Sagot :

When finding the area of triangle you need to use the formula A = 1/2 BH

Solution:

  • A = 1/2 BH
  • A = 1/2 (20cm) (30cm)
  • A = (10cm) (30cm)
  • A = 300cm²

Step-by-step explanation:

To find the area you must use the formula first and then after that you will now solve the problem make sure that before you will proceed to next step is that you multiply the base to 1/2, like what i do and then after that multiply the 10 to 30 which is equal to 300.

Hope this would help :)
