The area is greater than or equal to 8 square feet.

Answer 1

Step-by-step explanation:

x>= 1.6 ft

hope it is correct

Answer 2

Given:

The area is greater than or equal to 8 square feet.

Base of the triangle is x.

Height of the triangle is 10ft.

To represent: the missing dimension x in the form of inequality.

Solution:

Know that,

Area of the triangle $\[ = \frac{1}{2} \times base \times height\]$

Observe that from the question, The area is greater than or equal to 8 square feet.

Therefore,

$\[\frac{1}{2} \times Base \times height \ge 8\]$

$\[ \Rightarrow \frac{1}{2} \times x \times 10 \ge 8\]$

$\[ \Rightarrow 5x \ge 8\]$

$\[ \Rightarrow x \ge \frac{8}{5}\]$

$\[ \Rightarrow x \ge 1.6\]$

Hence, the missing dimension in form of inequality is $\[x \ge 1.6\]$.
