A company provides curtains at the rate of RS.50 per square feet. Measure all doors and windows of your home and determine the expenditure for all doors and windows required for your home.
Answers
Step-by-step explanation:
lets assume we have:
Door X1 ( l=3m b=1m)
WindowsX3 (each l=3m b=3m)
we know 1M=3.280 FEET we will take it as 3.8(appeox)
ar(door)= l×b = 3(4) = 12msq
ar(window)= a(a)= 3×3= 9msq
for 3 windows 9X3=27msq
Add all areas
27+12=39m sq
lets convert M to feet by multipling
39X3.8=148.2feet
since 1 feet is Rs.50
therefore, 50X148.2=7410
So Rs.7,410
Given : A company provides curtains at the rate of Rs 50 per square feet
To find : measure all doors and windows of your home and determine the expenditure for all the doors and windows required for your home
Solution:
Doors in House
Size Number Area of one ft² Area of all ft²
7 ft by 3 feet 10 21 210
6 ft by 2.5 feet 6 15 90
8 ft by 4 feet 1 32 32
Total Doors area 332
Windows in House
Size Number Area of one ft² Area of all ft²
4 ft by 3 feet 6 12 72
3 ft by 2 feet 6 6 36
Total Windows area 108
Total Area = 332 + 108 = 440 ft²
curtains rate = Rs 50 per square feet
Total expenditure 440 * 50 = Rs 22000
Expenditure for all the doors and windows required for home = Rs 22000
