For a circle its Pier Squared
2/3 x 12 is 8 hope this helped :)
Answer
8/12=4/6=2/3
When simplifying, if both the numerator and the denominator are even you can just divide them by two
Answer:
Perimeter = 42 cm.
Step-by-step explanation:
The 2 legs are equal in length as it is an isosceles trapezoid.
Area of trapezoid = (h/2)(a + b) where a and b are the parallel bases.
So
(5/2) (a + b) = 45
a + b = 45 * 2/5 = 18 cm.
We are given that the length of a leg (L) is 2/3 * sum of the bases, so:
L = 2/3(a + b)
= 2/3 * 18
= 12 cm.
The perimeter = a + b + 2L
= 18 * 2*12
= 42 cm.
Answer:
The slope of the perpendicular line is 1/4
A line parallel to this will have the same gradient of -4.
