Answer:
14 cm²
Step-by-step explanation:
Obtuse angle: more than 90° and less than 180°
The formula for the area of an obtuse triangle is the same as that for any triangle:
- area of a triangle = 1/2 x base x height
Therefore, given:
⇒ area = 1/2 x 4 x 7 = 14 cm²
Answer:
solve for each variable then plug them in
Step-by-step explanation:
Answer:
For x = height:
x(x + 20) = 576.
Step-by-step explanation:
The area is 576 cm^
Area = width * height
Let the height be x, then the width is (x + 20) cm
So the expression for the area can be written
x(x + 20) = 576.
