The area of a rectangle is 24 square inches. The rectangle is 6 inches long. How wide is the rectangle? A.10 inches
B.2 inches
C.4 inches
D.18 inches

c. 4 inches

Step-by-step explanation:

6 times 4 is 24 inches

The correct answer is C. 4 inches

Step-by-step explanation:

We know the area is 24 square inches.

We know that the rectangle is 6 inches long.

Remember that the formula for the area of a rectangle is length × width

1. Plug in the length and area into the formula:

6 × width = 24

2. Solve for width to get your

Divide each side by 6

(6 × width)/6 = 24/6

width = 4

3. Plug 4 back into the equation to check your solution:

6 × 4 = 24

true

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
