**1.Find the perimeter of a rectangular field which is 40 m long and 20 m wide.**

**Sol. l =40 m , b= 20 m, Perimeter = 2(l+b), p= 2(40+20)= 120 m**

**2.Find breadth of rectangle whose perimeter is 120m and length is 36m.**

**Sol. P= 120m , l = 36m Perimeter = 2(l+b)**

**120 = 2(36 + b) = 72 + 2b**

**2b = 120 – 72 = 48**

**B= 48/2 = 24 m**

**3. Find the length of a rectangle whose perimeter is 100 cm and breadth is 15cm.**

**Sol. P= 100cm , b = 15cm Perimeter = 2(l+b)**

**100 = 2(l + 15) = 2l + 30**

**2l = 100 – 30 = 70**

**l= 70/2 = 35cm**

**4.Find the area of a rectangle whose length is 5m and breadth 45cm.**

**Sol. length is 5m, breadth 45cm. Area = l x b = 5 x 45=225**

**5. The area of rectangular garden which is 52 meters long is 1820sq.m. find the width of the garden.**

**Sol. Area of rectangle = 1820 sq.m**

**Lngth of the rectangle = 52 m**

**Width = Area / length = 1820/52 = 35 meters.**

**6. Find the length of the rectangular plot whose breadth is 40m and area is 3600 sq.m**

**Sol. Area of rectangle = 3600 sq.m**

**breadth of the rectangle = 40 m**

**length = Area / breadth = 3600/40 = 90 meters.**

**7. Find the cost of fencing of a square part of side 200m at the rate of Rs. 20 Per meter.**

**Sol. Permiter of the park = 4 s = 4 x 200 = 800m**

**Cost of fencing for one meter of park = Rs. 20-00**

**Total cost of the fencing of the park: 20 x 800=16000**

**Side of the square park = 50m**

**Perimeter of the park = 4 x s = 4x 50 = 200m**

**Distance covered by rama= 200m, L= 60 and b=45**

**Perimeter of the park= 2(l + b)= 2(60 + 45) = 210m**

**Bulbul covers more distance.**

**L = 3.5, perimeter of square = 4s = 4 x 3.5 = 14 cm.**

**Length of the roupe 4 sides = 14 x 4= 56cm.**

**Cost of rope required at Rs. 15 permeter = 56 x15= Rs. 840**

**Length of wire = 60m**

**The perimeter of an equilateral triangle with side let x**

**3x = 60 There fore x = 20**

**An equilateral triangle side = 20 cm**

**Perimeter of ‘square = 4s = 4x**

**Length of wire = 60m**

**ii)a square 4x = 60 There fore x= 60/4 =15**

**Length of wire = 60m**

**The perimeter of the regular hexagon with six “x” cm**

**6x = 60 x =60/6 = 10**

**iii)a regular hexagon = 10**

**The perimeter of the regular pentagon with five “x” cm**

**ix) a regular pentagon. 5x = 60 x= 60/5 = 12cm**
