Answer:
52
Step-by-step explanation:
<em>What we know:</em>
<em>total rectangle area = yellow area + red</em>
length of total (yellow + red) rectangle: 11 units
width of total (yellow + red) rectangle: 6 units
length of red rectangle: 7 units
width of red rectangle 2 units
formula for area of rectangle: l x w
<em>solve:</em>
area of yellow only = total area - red rectangle
A = l x w (of total) - l x w (of red)
A = (11 x 66) - (7 x 2)
A = 66 - 14
A = 52
ans. the area of the yellow shaded region is 52
