Question

Find the height of a triangle if the base is 15cm and the area is 64.5cm²

Also find the base of the triangle if the height is 12cm and the area is 79.2cm²

Give the answer with explanation

​

Answer 1

Answer:

solution 1.

Step-by-step explanation:

Base=15cm

Area of triangle =64.5cm^2

Area of triangle=1/2×base ×height

64.5=1/2×15×height

64.5×2/15=height

12.9×2 =height

height = 25.8cm

solution 2.

Height =12cm

Area of triangle=79.2cm^2

Area of triangle =1/2base×height

79.2 = 1/2×base×12

79.2×2/12 = base

158.4 /12 = base

base=13.2cm
