Question

The length of a rectangle is 61 m-17 n and its breadth is 15n+27m.Find its perimeter​

Answer 1

Answer:

174m - 4n.

Step-by-step explanation:

Answer 2

Answer:176m -19n

Step-by-step explanation: the perimeter of the rectangle is 2(l+b)

So it will be 2(61m-17n+15n+27m)

When we take the *like terms to one one side 2(61m+27m+(-17n+12n))

We take the additive inverse of 17 and 12 we will get -17+12so we get

We get 2(88m -5n)

The perimeter of the rectangle is 176m-10n
