Answer:
157.14 cm
Step-by-step explanation:
1/2 ×22/7 ×10 ×10= 157.14 cm
Area by Heron's formula:
semiperimeter = (15 + 20 + 25)/2 = 60/2 = 30 cm

The formula of the area of a triangle: Area = 1/2 * base * height
1/2 * 25 * height = 150
12.5 * height = 150
height = 150/12.5
height = 12 cm
X = 0.89
x = -0.89

Well, Mathematics can enhance your analytical and problem-solving skills, expands the mind to handle difficult or unfamiliar tasks, and also promotes cautious and careful thinking. Once you know what the words mean you'll be able to write different variable expressions. Like I said it enhances our minds and helps think and solve probelms.
