**Important questions based on NCERT syllabus for Class 7 Chapter 11 - Perimeter and Area:**

*Question 1*: From the given information calculate the area of the triangle. Given height of the triangle is 5 cm and it divides the base into two equal parts of 3 cm each. Express your answer in m^2 .

*Solution*: Height = 5cm

Given base is divided into two equal parts, so base length = 3+3 = 6cm

Area of the triangle = (1/2) x base x height

= (1/2)x(5/100)x(6/100)

= (15/10000)

= 0.0015

= 0.0015 m^2

*Question 2*: If a stick given is of length 628 m is bent in the form a circle and later bent into a square .which of these Circle or square have greater area ?

*Solution*:

Length of the stick is equal to perimeter of circle and square individually.

Circle of given radius has perimeter of 628 m

Radius of the given circle = (628/(2xπ))

= 100 m

Area of the circle = (π)x(r)^2

=(π)x(100)^2

=(3.14)x(100)^2

=31400 m^2

*Question 3*: Given a man is walking in a circular park , in one revolution he completes 314 m . If there is a man In the opposite end of the diameter which is drawn from the point where the man is standing . Find The minimum distance he has to walk to meet his friend who is sitting on the described point ?

*Solution*:

Circumference of the circle = 314 m

Radius of the given circle = (314/(2xπ))

= 50 m

Diameter is what has been aske to find Diameter = (2)x(50)

= 100 m
