Perimeter and Area
The length and the breadth of a rectangular piece of land are 500 m and 300 m respectively. Find
(i) its area
(ii)the cost of the land, if 1 m2 of the land costs Rs 10,000.
(i) Area = Length × Breadth
= 500 × 300
= 150000 m2
(ii)Cost of 1 m2 land = Rs 10000
Cost of 150000 m2 land = 10000 × 150000 = Rs 1500000000
Find the area of a square park whose perimeter is 320 m.
Perimeter = 320 m
4 × Length of the side of park = 320
Length of the side of park =
Area = (Length of the side of park)2 = (80)2 = 6400 m2
Find the breadth of a rectangular plot of land, if its area is 440 m2 and the length is 22 m. Also find its perimeter.
Area = Length × Breadth = 440 m2
22 × Breadth = 440
Breadth == 20 m
Perimeter = 2 (Length + Breadth)
= 2 (22 + 20) = 2 (42) = 84 m2
The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth. Also find the area.
Perimeter = 2 (Length + Breadth) = 100 cm
2 (35 + Breadth) = 100
35 + B = 50
B = 50 − 35 = 15 cm
Area = Length × Breadth = 35 × 15 = 525 cm2
