Question

the length of a rectangle is 5 and more than its breadth if the perimeter of the rectangle is 96 cm find the length and breath of the rectangle

Answer 1

Answer:

$breadth \: = b \\ length \: = l = b + 5 \\ perimeter \: = 96 \\ = > 2(l + b) = 96 \\ = > 2(2b + 5) = 96 \\ = > 2b + 5 = \frac{96}{2} = 48 \\ = > 2b = 48 - 5 = 43 \\ b = 21.5 \\ l = b + 5 = 21.5 + 5 = 26.5$
