-3b=96+b -4b=96 b=-24
-3b = 96 + b Subtract b from both sides: -4b = 96 Divide both sides by -4: b = -24
we have the formula to find perimeter of the rectangle i.e. perimeter = 2(l+b) where l = length b = breadth substitute l=96 and perimeter = 334,we get 334 = 2(96+b) 334/2=96+b, 167 = 96 + b b = 167-96 =71. b = breadth of the given rectangle is 71.
-3b=96+b Well, first you could subtract "b" from each side, and then you'd have -4b=96, and then you could divide by 4 on each side and get your answer for "b"
(a + b)(a - b) = a2 - b2 for example if a = 10 and b = 2 12 x 8 = 96 = 100 - 4
