If the area of a rectangular plot is 144 sq. m. and its length is 16 m, find the breadth of the plot. Also find the cost of painting a blue border around the plot if the cost is ₹ 3 per metre. About the author Sadie
Given: Length =16m Area of Rectangle = Length× Breadth 144 m² = 16× Breadth Breadth = 144/16 Breadth = 9 cm Perimeter of Rectangle = 2(l+b) = 2 (16+9) = 2×25 = 50 m cost of 1m = ₹3 cost of 50m = 50×3 = ₹ 150 Reply
area of rec is l*b
144=16*?
?=9m
perimeter=2(l+b)
2(16+9)
50m
cost of paining=50*3=150
Given: Length =16m
Area of Rectangle = Length× Breadth
144 m² = 16× Breadth
Breadth = 144/16
Breadth = 9 cm
Perimeter of Rectangle = 2(l+b)
= 2 (16+9)
= 2×25
= 50 m
cost of 1m = ₹3
cost of 50m = 50×3
= ₹ 150
