7. Perimeter of an equilateral triangle is 54 cm and length of the side of the triangle is 3 cm less than the radius of a circle. Find the difference between the circumference of the circle and perimeter of the triangle

a. 78cm
b. 68cm
c. 58cm
d. 88cm

= 21 cm
Circumference of circle = 2 × π × 21
= 132 cm
Required difference = 132 – 54
= 78 cm

11. The perimeter of a rectangular table is 60 cm. If the area of the rectangular table is 209 cm², then what will be the length of the table?

a. 17 cm
b. 19 cm
c. 13 cm
d. 21 cm
e. None

Answer: b

Explanation:

Perimeter of a rectangular table = 60 cm
Area of the rectangular table = 209 cm2
Let length of the table = x cm
Breadth of the table = y cm
According to question,
⇒ 2(x + y) = 60 cm
⇒ x + y = 30 cm………….(1)
⇒ xy = 209 cm2…………….(2)
Now, we know that-
(x+y)2 = (x−y)2 + 4xy
⇒ (30)2 = (x−y)2 + 4×209
⇒ (x−y)2 = 900−836 = 64
⇒ x−y = 8 ……..(3)
Adding (1) and (3)
⇒ 2x = 38 cm
⇒ x = 19 cm
Length of the table = 19 cm
