Answer:
Step-by-step explanation:
Area of parallelogram = base * height
= 12 * 8
= 96 cm²
Area of parallelogram = 96
base * height = 96
base = 96/height
base = 96/16
base = 6 cm
Answer:
x = 12, x = 7
Step-by-step explanation:
The 2 legs of the triangle are congruent, both 2x + 7, then
2x + 7 + 2x + 7 + x + 11 = 85 ← equation for perimeter
5x + 25 = 85 ( subtract 25 from both sides )
5x = 60 ( divide both sides by 5 )
x = 12
-----------------------------------------------------------
Opposite sides are congruent, then
2(2x) + 2(5x + 3) = 104 ← distribute and simplify both sides
4x + 10x + 6 = 104
14x + 6 = 104 ( subtract 6 from both sides )
14x = 98 ( divide both sides by 14 )
x = 7
The correct way is to plug in the answer back into the equation and see if it results in the correct solution.
