Mortimer wants to change the shape of his garden. the garden is now 3 feet longer than its wide, but if he increases the length by 4 feet and decreases the width by 1 feet, he will gain 8ft^2 in area. what are the original dimensions of the garden?

The original dimensions of the garden are

Length

Width

Step-by-step explanation:

Let

x-----> the original length of the garden

y-----> the original width of the garden

we know that

-----> equation A

The original area is equal to

substitute equation A

if he increases the length by 4 feet and decreases the width by 1 feet, he will gain 8ft^2 in area

so

The new area is equal to

substitute equation A

Remember that

substitute the values

find the value of x

therefore

The original dimensions of the garden are

Length

Width

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.
