Question

Area of rectangle is x6-1 and it's breadth is (x-1) then it's length is ​

Answer 1

First we have to make our mathematical sentence from the data provided to figure the width which we will call X. We will use X for width (breath) and use 2X for length since length is twice the length of width. We also know there is 2 lengths and 2 widths to equal the perimeter.

Our sentence will be as follow: 2(2X)+2(X)=60m. Lets start working the sentence to find X.
