Answer:
Length 7 feet and Width 5 feet
Step-by-step explanation:
we know that
The area of the rectangle ( a dining room table) is equal to
where
substitute
Apply difference of squares right side
Remember that the length cannot be a negative number
so
x=2
<em>Find the length</em>
<em>Find the width </em>
Since you already have the circumference, you will divide 56 (Circumference) by pi. Which will get you the diameter*

Answer: The required length of the golden thread needed is 30 cm.
Step-by-step explanation: Given that a triangular colorful scenery is made in a wall with sides 50 cm, 50 cm and 80 cm. A golden thread is to hang from the vertex so as to just reach the side 80 cm.
We are to find the length of the golden thread required.
As shown in the attached figure below, ABC is the triangular scenery with sides
AB = AC = 50 cm and BC = 80 cm.
AD is drawn perpendicular to BC, so that AD is the length of the golden thread required to reach side BC with length 80 cm from the vertex A.
Now, since AD ⊥ BC and ΔABC is isosceles (AB = AC), so we must have
D is the midpoint of BC.
That is,
Now, from the right-angled triangle ABD, we have
Thus, the required length of the golden thread needed is 30 cm.
