Answers
Answer:
it's answer is 2000 by bricks
The width of the 57 m long lane which is paved with bricks of size 20 cm x 15 cm is 21 m.
Explanation:
Step 1:
The total cost of the bricks = Rs. 89.775
The rate of bricks is given as Rs. 2.250 per thousand
∴ The no. of bricks used for paving the lane is,
= [89.775/2.250] * 1000
= 39900
Step 2:
The dimension of each brick:
Length, l = 20 cm
Breadth, b = 15 cm
∴ Area of each brick = l * b = 20 * 15 = 300 cm²
∴ The total area of the lane made with 39900 bricks will be,
= 300 cm² * 39900
= 11,970,000 cm²
= 1197 m²
Step 3:
The length of the lane = 57 m
Let the width of the lane be “x” m
Therefore, we have
The area of the lane = 57 * x
⇒ 1197 = 57 * x
⇒ x = 21 m
Thus, the width of the lane is 21 m.
