Question

The perimeter of a rectangle is 30cm while it breadth is 5cm find the length of the rectangle

​

Answer 1

length = 10 cm

Explanation:

Fyi, breadth is a synonym to width.

Since P=30, we must find the length.
l = length
w = width
P=w+w+l+l

30 = 5+5+l+l
30 = 10+2l
-2l = -20
l = 10

Hence, the length is 10 cm.
