A. the total area of the model is 130 m2. write an equation to find x.b. solve the equation by completing the square. (x + 2)(2x + 2) = 130; x = 5.12 m (x + 2)(2x + 2) = 130; x = 6.70 m (x + 2)(2x + 2) = 130; x = 6.58 m (x + 2)(x + 2) = 130; x = 9.40 m
Accepted Solution
A:
the complete question in the attached figure
we know that
[area of rectangle]=b*h b=(x+2) h=(2x+2) Area=130 m²
