12.) A rectangular garden bas a perimeter of 50 feet. The width of the garden is 7 feet. What is the area of the garden? 50 feet xi feet A. 18 ft? B. . 126 ft C. 50 ft D 350 ft​

126

Step-by-step explanation:

Perimeter=2(l+w)

50/2=2525-w

25-7=18

Area= lxw

18x7=126

b

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
