Each of the four angles of a quadrilateral measures 90°.
<u>Only</u><u> </u><u>1</u><u> </u>
we can construct using this condition.
as interior angle of quadrilateral and rectangle is 360°
Answer: root of 18
9+9=x^2
18=x^2
x = 3 root of 2 or root of 18
Area of trapezoid = 1/2(b1+b2)h
b1 and b2 are top and bottom bases
so b1 = 15.8 and b2 = 21.8
h is height so h = 11.7
so
A = 1/2(15.8 + 21.8)(11.7)
A = 1/2(37.6)(11.7)
A = 219.96
answer
D. 219.96 yd^2
