The area of a triangle is found with 1/2(b x h).
a = 1/2(4 x 14)
Multiply 4 by 14.
a = 1/2(56)
Multiply 56 by 1/2.
a = 28
The area of the triangle is 28 square units, hope this helps!
Answer:
a = 9.4 cm
b = 12.0 cm
Step-by-step explanation:
Check the image uploaded for diagram;
For the first diagram, side length a is calculated as follows;
a² = 8² + 5²
a² = 64 + 25
a² = 89
a = √89
a = 9.4 cm ( approximated to 1 decimal place)
For the second diagram, side length b is calculated as follows;
b² = 17² - 12²
b² = 145
b = √145
b = 12.0 cm (approximated to 1 decimal place)
Answer:
A = 1/2(b×h)
