The total cost of leveling a school’s rectangular ground is ₹3050. If the breadth of the ground is 20 m and the cost of levelling is ₹2.50 per sq.m, find the length of the ground.
Answers
Answer:
width of rectangle ground = 24 m
Step-by-step explanation:
the cost of levelling rectangular ground at rs 1. 25 per m२ is rs 900
.total cost of levelling rectangular ground = rs 900
cost rate of levelling rectangular ground per m^2 = 1.25 rs
Area of rectangular garden = total cost of levelling rectangular ground / cost rate of levelling rectangular ground per m^2
= 900/1.25
= 720 m^2
length of ground = 30 m
area of rectangle = length × width
width of ground = area of ground / length of ground
width of ground = 720/30 = 24 m

plz Mark me the BRAINIEST
Step-by-step explanation:
area of rectangular field = L×B
Coast of levelling= 2.50 rupees
Total coast of levelling a school's ground = area of ground × coast of levelling
= L × 20 × 2.50 = 3050
= L × 59 = 3050
= L = 3050/50
= L = 61
Therefore, length of the ground is 61 m
