a) area of a triangle = (base X height) / 2 = 16X9/2 = 72cm squared
b) area of a parallelogram = (base X height) = 26 X 14 = 364 in squared
c) area of a square = (base X width) = 11 X 11 - 121 yds sqaured
d) are of a trapezoid (the hardest) =
(top bases + bottom base) /2 all times height
(6 + 21) /2 times 8
126/2 times 8
63 times 8 = 504 ' squared
Answer:
x = 21.6
Step-by-step explanation:
<u>Solution by Cross Multiplication</u>
For the equation
35=x36
The cross product is
3×36=5×x
Solving for x
x=3×365
and reducing
x=21.6
<u>Solution by Proportion</u>
Since the equation is an equality
If
36 ÷ 5 = 7.2
Then it is true that
x ÷ 3 = 7.2
Solving for x
x = 3 × 7.2
x = 21.6
It's A. When you reduce between the x exponents in the original you get an xcubed on top. In A, when you reduce between the x exponents you get xcubed on bottom and they cancel each other out.
