length of its side (a).
b. The sum of the four angles (a, b, c, d) of a
quadrilateral is 360°
c. The area (A) of a parallelogram is the
product of its base (b) and height (h).
d. The area (A) of a triangle is equal to half of the product of its base (b) and height (b) .

Answers & Comments
1. P = 4 × a → 4a
2. a + b + c + d = 360°
3. A = b × h
4.
[tex]a \: = \frac{1}{2} \times b \times h \: \\ \: \: \: \: \: \: \: \: \: \: \: \: or \\ \\ a \: = \: \frac{1}{2} \times bh \\ \\ \\ \\ \\ [/tex]
Hope Helps You
Answer:
A. 4×a=P
(P=4×a)
B. a+b+c+d=360°
C. A=base×height
D.
[tex]a = \frac{1}{2} \times base \times height[/tex] or 1/2bh
