The perimeter of a rectangle is 30cm. The length is 3cm more than twice the width. Find the LENGTH of the rectangle

(2w+3)2+2w=30

4w+6+2w=30

6w=30-6=24

w=4

l=4(2)+3

l=11

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
