The length of a rectangle is 8cm more than 3 times it’s width. the perimeter of the rectangle is 64cm

The length is 26 cm, and the width is 6 cm.

Step-by-step explanation:

The width is unknown. Let w = width.

The length is 8 cm more than 3 times the width.

length = 3w + 8

The perimeter is 64 cm.

P = length + length + width + width

3w + 8 + 3w + 8 + w + w = 64

8w + 16 = 64

8w = 48

w = 6

The width is 6 cm.

length = 3w + 8 = 3(6) + 8 = 18 + 8 = 26

The length is 26 cm

< 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
