Asquare room is 15 m long, find the are of floor

225 square meters

Step-by-step explanation:

Area of a square:

A = w², where w is the width of the square

Plug in values:

A = 15m²

A = 225 square meters

A = 225

Step-by-step explanation:

The area of a square is;

A =

A = Length * Length

A =

A = 15m * 15m

A = 225

the anwser is d) 75°

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
