Answer:
Step-by-step explanation:
Given:
Length (l) = 12 cm
Width (w) = 4 cm
Perimeter of the rectangle = 2(l + w) units
<em>P</em> = 2(12 + 4)
<em>P</em> = 2 (16)
<em>P</em> = 32
the answer is b -2u +w
or -2w - u
9a - 2b
6a - 6b +3a +4b . . . . . . . we assume your _ is supposed to be -
= a(6 +3) +b(-6 +4)
= 9a -2b
