Question

The area of a rectangle is a 40 square inches. The width of the rectangle is 4 inches more than the length. What are the dimensions of the rectangle?

Answer 1

Answer:

I think 10

Step-by-step explanation:

because 4 times 10 is 40 and 4 side so 10 for each side

Answer 2

The dimensions of the rectangle are 4.63 inches and 8.63 inches respectively.

• Let the length of the rectangle be L.

• Let the width of the rectangle be W.

Given the following data:

• Area of a rectangle = 40 square inches.

Translating the word problem into an algebraic equation, we have;

$W = L + 4$

To find the dimensions of the rectangle:

Mathematically, the area of a rectangle is given by the formula;

$Area = LW$

Substituting the values into the formula, we have;

$40 = L(L+4)\\\\40 =L^2+ 4L\\\\L^2+ 4L -40=0$

Solving the quadratic equation by using the quadratic formula, we have the following values;

L = 4.63 or −8.63

Length, L = 4.63 inches.

For the width:

$W = L + 4$

$W = 4.63 + 4$

W = 8.63 inches
