the length of a rectangle is 4 feet longer than twice the width of the same rectangle. if the perimeter of the rectangle is 68 f
Rom4ik [11]

Represent the length and width by L and W.  Then L = W + 4.

Using the perimeter formula:  P = 2L + 2W = 68 ft = 2W) + 2(W+4).

Solve for W:  68 = 2W + 2W + 8, or 4W = 60.  Thus, W = 15 and L = 19.

The dimensions of the rectangle are 15 by 19 feet.

MrRa [10]

Answer:

Option (2). None

Step-by-step explanation:

A quadrilateral ABCD has been given with a property,

m∠7 = m∠4

Option (1). AB║ DC

For AB║DC, angle 7 and angle 3 should measure the same.

(By the property of alternate angles)

Therefore, by the given property we can not deduce AB║DC.

Option (3). AD║BC

For AD║BC, angle 7 and angle 3 must be equal in measure.

(By the property of alternate angles)

Therefore, by the given property we can not deduce AD║DC

Option (2). None will be the answer.

4b + 5 = 1 + 5b <br><br> what is b?
Alla [95]

Answer: b = 4

Step-by-step explanation:

<u>Given</u>

4b + 5 = 1 + 5b

<u>Subtract 4b on both sides</u>

4b + 5 - 4b = 1 + 5b - 4b

5 = 1 + b

<u>Subtract 1 on both sides</u>

5 - 1 = 1 + b - 1

\boxed{b=4}

Calculate the area of this triangle :
nordsb [41]

Applying it's formula, the area of the given triangle is of 30 centimeters squared, that is, 30 cm².

<h3>What is the area of a triangle?</h3>

The area of a triangle of base b and height h is given by half the multiplication of these measures, that is:

A = 0.5bh.

In this problem, we have that b = 12 cm, h = 5 cm, hence:

A = 0.5 x 12 cm x 5 cm = 30 cm².
