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.
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.
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
Hope this helps!! :)

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.
