Answer:
Area of the parallelogram = 21.6 cm²
Step-by-step explanation:
Area of a parallelogram = Base × Height of the side parallel to the base
By using ruler,
Base = 4.8 cm
Height of parallelogram = 4.5 cm
Area of the parallelogram = 4.8 × 4.5
= 21.6 cm²
Answer:
base -l*b - 13*6.5 - 84.5
Answer:
Step-by-step explanation:
3x + x + 60 = 180.
first, we add the x's together.
4x + 60 = 180
then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.
x + 15 = 45
then, just subtract 15 from both sides, that way we get the variable by itself.
x = 30
also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
The answer is 246 units²
