Answer:the length of the land is 25 meters.
the width of the land is 20 meters.
Explanation:
The land on which Elliot wants to build is rectangular in shape.
Let L represent the length of the land.
Let W represent the width of the land.
He knows that the length is five more meters than the width. This means that
L = W + 5
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
He knows that the perimeter is 90 meters. This means that
2(L + W) = 90
L + W = 90/2 = 45
Substituting L = W + 5 into L + W = 45, it becomes
W + 5 + W = 45
2W + 5 = 45
2W = 45 - 5 = 40
W = 40/2 = 20
L = W + 5 = 20 + 5 = 25
