Area of a square is side length ^2

To find the length of the side of a square from the area, that’s the square root of the area:

Length of side = sqrt(81) = 9 meters

Area of wall = length of side x height:

Area of wall = 9 x 5 = 45 square meters

Answer: 45 square meters

Which inequality is shown in this graph
Katena32 [7]

ANSWER

y \leqslant   - 2x - 2

EXPLANATION

The boundary line passes through (-2,2) and (0,-2).

The slope of this line is

m =  \frac{ - 2 - 2}{0 -  - 2}

m =  \frac{ - 4}{2}  =  - 2

The y-intercept is , c=-2.

The slope-intercept form of this line is given by;

y = mx + c

We substitute values to obtain;

y =  - 2x - 2

Since the lower half-plane is shaded the required inequality is

y \leqslant   - 2x - 2
