Alright, lets get started.
I hope, the dimensions of rectange are asked in this question.
Suppose the width of rectangle = x in
Given that length of the rectangle is 3 in longer than the width.
It means length of the rectangle = (x+3) in
Now, the area of the rectangle = lenght * width
area of the rectangle =
area of the rectangle =
The area of a rectangle is 70 in square (given in question)
Equalling both areas
Subtracting 70 in both sides
Factoring
It will give two values of x
x = -10 (which is not possible because length could not be negative)
x = 7
Means width
length
Means the dimensions of rectangle are 7 in and 10 in. : Answer
Hope it will help :)
