Question

The area is no more than 40 square feet. Write and solve an inequality that represents the value of x

Answer 1

well its a triangle so

40 divide by 20 is 2

but you have to mutiply that 2 by 2

Explanation:

4

Answer 2

The inequality expression which represents the value of x is : 40 <= 0.5 * 20 * x² and x >= 2

The area of the triangle is related by the formula ;

• Area = 0.5 × base × height
• Area <= 40 ft²

Now we have ;

40 <= 0.5 * 20 * x²

40 <= 10x²

40/10 <= 10x²/10

4 <= x²

√4 <= √x²

2 <= x

x >= 2

Hence, the value of x >= 2
