Question

Write the following statements as formulae:
a. The perimeter of a square (P) is 4 times the
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) .​​

Answer 1

1. P = 4 × a → 4a

2. a + b + c + d = 360°

3. A = b × h

4.

$a \: = \frac{1}{2} \times b \times h \: \\ \: \: \: \: \: \: \: \: \: \: \: \: or \\ \\ a \: = \: \frac{1}{2} \times bh$

Hope Helps You

Answer 2

Answer:

A. 4×a=P

(P=4×a)

B. a+b+c+d=360°

C. A=base×height

D.

$a = \frac{1}{2} \times base \times height$ or 1/2bh
