Answer:
17
Step-by-step explanation:
4w = w + 51
3w = 51
w = 51 : 3
w = 17
I think it's D as an answer but I could be wrong
Answer: =2084
4+2(82)(42)+6+4+6+6+6+2+2
=4+264(42)+6+4+6+6+6+2+2
=4+2(64)(16)+6+4+6+6+6+2+2
=4+(2)(1024)+6+4+6+6+6+2+2
=4+2048+6+4+6+6+6+2+2
=2052+6+4+6+6+6+2+2
=2058+4+6+6+6+2+2
=2062+6+6+6+2+2
=2068+6+6+2+2
=2074+6+2+2
=2080+2+2
=2082+2
=2084
Area of trapezoid = a + b/2 * h
a = 20, b = 9, h = 21/-16
20+9/2 * (21-16) = 29/2 * 5 = 72.5
The area of the trapezoid = 72.5 in^2
Area of the rectangle = l * w
l = 16, w = 20
16 * 20 = 320
The area of the rectangle: 320 in^2
