ANSWER: 208 cm
first find the area of the small rectangle:
a = w • l
w = 15 - 4 = 11
l = 30 - 8 =22
a = 22 • 11 = 242
now, find the area of the large rectangle:
a = 30 • 15 = 450
now subtract the small area from the large to find the shaded area:
450 - 242 = 208 cm
I did this quickly so I apologize if I made any errors!
