A door 2.1 X 1m is fitted in a wall. length of the wall is 6.5 m and the height is 4 m find the cost of plastering the wall if the rate of plastering the wall is ₹ 10 per m2
Answers
Answer:
239
Step-by-step explanation:
Length of door = 2.1 m , breadth of door = 1 m.
Area of door = length * breadth
= 2.1 * 1
= 2.1 m²
Length of wall = 6.5 m, breadth of wall = 4 m.
Area of wall = 6.5 * 4
= 26 m²
Area of wall including door - Area of wall
= 26 - 2.1
= 23.9 m²
The cost of plastering the wall per m² = 10.
The rate of plastering the wall 23.9 per m² = 10 * 23.9
= 239.
Hope it helps you.

hey there
here ur answer
Given:
Length of door = 2.1 m
1st breadth of door = 1 m.
Length of wall = 6.5 m
breadth of wall = 4 m.
Solution:
Calculating for door:
Area of door = length × breadth
= 2.1 × 1
= 2.1 m²
thn,
Calculation for wall :
Area of wall = length × breadth
= 6.5 × 4
= 26 m²
So,
→ 26 - 2.1
→ 23.9 m²
∴ The cost of plastering the wall per m² is 10.
The rate of plastering the wall 23.9 per m² = 10 × 23.9
= 239.
∴The rate of plastering the wall 23.9 per m² is 239.
