Answer:
22 yd
Step-by-step explanation:
Length is four times its width -----> L=4W
area of rectangle is 196 -----> 196=LW
Plug L=4W into 196=LW giving you 196=(4W)W
Simplify a bit 196=4W^2
Divide both sides by 4: 196/4=W^2
Simplify a bit: 49=W^2
Square root both sides: 7 or -7=W
The width is 7 yd
The length is 4(7)=28 yd
Now its final part is for you to find the perimeter of this rectangle. The rectangle is a 7 yd by 4 yd rectangle.
Double both then add.. 14+8=22 yd
Isosceles trapezoid
<ONM = <LON = 100
<OLM = <NML = 1/2(360 - 2(100))
= 1/2(360 - 200)
= 1/2(160)
= 80
Answer
<OLM = 80 degress
