Find the length of a rectangular field, given that its breadth is 50 m and the cost of turfing it at 41.25 per m² is 154687.50.
Answers
Answer:
Length of the rectangle = 75 metres
Step-by-step explanation:
Given: Breadth of the rectangle = 50 metres
Cost of turfing = 154687.50
Rate of turfing = 41.25 per m²
Find: Find the length of the rectangle
Step 1: Find the area of the rectangle by using rate and cost.
Area of the rectangle = 154687.50÷41.25 = 3750 m²
So, the area of rectangle = 3750 m²
Step 2: Find length by using the area of the rectangle
Area of any rectangle = length × breadth
3750 = length× 50
Length = 3750 ÷ 50
l = 75
Length of the rectangle = 75 metres
Answer:
Length of rectangular field is 75 m.
Step-by-step explanation:
Total cost of turfing =Rs.154687.50
Cost of turfing of 1 sq m. area=Rs.41.25
Area of rectangular field=total cost/cost per sq.m.
=154687.50/41.25
= 3750 sq. m.
Breadth of rectangular field (b) =50 m.
Area of rectangle=length× breadth
∴ Length of rectangular field=Area/breadth
=3750/50
=75 m.
