Question

Find the length of a rectangle given that its perimeter is 880 m and breadth is 88 m.

​

Answer 1

Answer:

We know that,

Perimeter of a rectangle = 2( length + breadth)

                                         = 2(l+b)

                             880     = 2 ( l + 88 )    (by substituting the known values)

So,                       880/2  = l + 88       (by transposing or taking the 2 to the other side)

                      880/2 - 88 = l             (by transposing or taking the 88 to the other side)

                          352 = l                   ( by simplifying)

The italicized words are to make you understand the steps.
