Im not sure what your teacher is asking you to communicate, but most simply would like to see evidence that you understand the material rather than simply looking up the answer... (i mean without reading an explanation xD)
4√x= √x*√x*√x*√xso √x • 4√x =5√x

Answer:
length is 26 and width is 23
Step-by-step explanation:
let width be x
then length is 3+x since it is 3 more than the width
perimeter of a rectangle = 2l + 2w
98=2 [3+x] + 2x
98=6+2x+2x
98=6+4x
98-6=4x
92=4x
x=23
width is 23 and
breadth is 26
