Mary crocheted a rectangular blanket whose diagonal measures approximately 7.21 feet. What are the most likely length and width measurements of the blanket ? Select the two correct answers.

Width = 1.77ft

Length = 6.98ft

See explanation below

Step-by-step explanation:

We can tell from the question, we are to find the the two possible lengths of a rectangle given the diagonal and the area. This question is not complete as it didn't indicate the area.

I would show you how to calculate the two possible lengths of a rectangle given the diagonal and the area.

Mary crocheted a rectangular blanket whose diagonal measures approximately 7.21 feet and area measures 12.4ft² approximately. What are the most likely length and width measurements of the blanket ?

The blanket is a rectangle

Diagonal = 7.21feet

Area measures = 12.4ft²

Formula for relating the diagonals to the length and width:

Diagonal² = length ² + width²

7.21² = l² + w²

l² = 7.21²-w²

l = √(7.21²-w²) ...equation 1

Area of a rectangle = length × breadth

12.4 = l × w ...equation 2

Substitute equation 1 in equation 2

12.4 = √(7.21²-w²) × w

12.4 = √(51.9841-w²) × w

Square both sides

12.4² = (51.9841-w²) × w²

153.76 = 51.9841w² - w⁴

w⁴ - 51.9841w² + 153.76 = 0

Using the almighty formula

Find attached the solution to the equation

From the solution width = 1.77ft or 6.98ft

Since width is shorter than length

Width = 1.77ft

Length = 6.98ft

The most likely length and width measurements of the blanket are 1.77ft and 6.98ft respectively.

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
