Question

The width of a rectangle is y feet long. The rectangle is 4 feet longer than it is wide. What is the area of the rectangle? Which expression represents the area? y(y + 4) sq ft y + 4 sq ft 4y sq ft y2 + 4 sq ft

Answer 1

y(y + 4) sq ft = is the answer

Answer 2

The area of the rectangle is y(4+y) feet² .

Explanation:

Formula

Area of the rectangle = Length × Breadth

As given

The width of a rectangle is y feet long. The rectangle is 4 feet longer than it is wide.

Breadth = y

Length = 4 + y

Putting all the values in the formula

Area of the rectangle = y × 4 + y

= y(4 + y) feet²

Therefore the area of the rectangle is y(4+y) feet² .
