A rectangular piece of carpet covers 10 yd^2. The width is 4 yd less than the length. Find the length and width.
Cerrena [4.2K]

Answer:

  • length: 5.7 yd
  • width: 1.7 yd

Step-by-step explanation:

Let w represent the width of the carpet. Then the length is w+4 and the area is ...

  w(w +4) = 10

  w² +4w = 10 . . . . . eliminate parentheses

  w² +4w +4 = 14 . . . . . . add the square of half the w-coefficient to complete the square

  (w +2)² = 14 . . . . . . . . . rewrite as a square

  w +2 = √14 . . . . . . . . . take the square root

  2 = -2 +√14 ≈ 1.7 . . . . yards (width)

Then the length is 4 more yards than this, so is ...

  length = 1.7 +4 = 5.7 . . . yards

The length and width are 5.7 and 1.7 yards, respectively.

_____

In the attached graph, we let x represent the length. As you can see, the magnitudes of the two zeros are width and length.

The diagonals of a parallelogram ABCD intersect at O.find ar(AOB),if ar(ABCD)is 44cm^2
prisoha [69]

Answer:

11\text{ cm}^2

Step-by-step explanation:

Given: In a parallelogram ABCD, diagonals intersect at O and ar(ABCD) is 44 \text{cm}^2.

We need to find the area of triangle AOB.

We know that each diagonal divide the parallelogram in two equal parts and diagonals bisect each other.

It means both diagonals divide the parallelogram in 4 equal parts.

ar(AOB)=\dfrac{1}{4}\times ar(ABCD)

ar(AOB)=\dfrac{1}{4}\times 44

ar(AOB)=11

Hence, the values of ar(AOB) is 11\text{ cm}^2.
