The answer is 0.1 i think

<h3>area of shaded figure= </h3>
<h2>area of whole rectangle</h2>
= lengthx breadth=15x30= 450 cm²
<h3>area of unshaded region= lengthx breadth= (30-8)x 15cm²= 22x 15cm²= 330cm²</h3>
<h3>are of shaded region</h3>
= area of whole rectangle -area of unshaded region= 450cm²-330cm²= 120cm²
therefore 120 is correct answer
Answer:
5x + 2y = 9
Step-by-step explanation:
Find the slope of the line that is perpendicular to 2x - 5y = 7 :
m= 
Find the y - intercept of the function:
b = 
substitute m=
and b =
into y = mx + b :
y =
+ 
y = 5x + 2y = 9
A three by three dot grid box would make a box with a height and length of two boxes, so the area of this would be 4.
