Question

Length of rectangle is 5 more than its breadth If the perimeter of rectangle is 170cm find the dimensions of the rectangle

Answer 1

Here is your answer

Let the breadth is x
so length is x + 5

Perimeter = 2(L + B)
$170 = 2(x + 5 + x) \\ 170 = 2(2x + 5) \\ 170 = 4x + 10 \\ 4x = 170 - 10 \\ x = \frac{160}{4} \\ x = 40$
So Length =40 + 5 =45 cm
and Breadth = 40 cm

Hope it helps you
