Question

Find the perimeter and area of a rectangular strip of land of length 1.4 km and width 75 m.

Answer 1

Answer:

2950, 105000

Step-by-step explanation:

perimeter of the rectangle 2(l+b)

lenght =1.4km = 1400m

breadth= 75m

perimeter = 2 ( 1400 +75)

= 2 × 1475

= 2950

Area of a rectangle = l × b

= 1400 ×75

= 105000

Answer 2

Answer:

perimeter = 2950 km, Area = 105000 square km

Step-by-step explanation:

length of rectangular strip = 1.4 km

Width of rectangular strip = 75 m

1.4 km = 1.4 x 100

          = 1400 m

Perimeter of rectangle = 2 x (length + width)

                                      = 2 x (1400 m + 75 m)

                                      = 2 x 1475 m

                                      = 2950 m (answer)

Area of rectangle = length x width

                             = 1400 m x 75 m

                             = 105000 sq m

Therefore, the perimeter of rectangular strip of land is 2950 m and its are is 105000 sq m.
