Answer:
The cost of the tile for the kitchen is $1,680
Step-by-step explanation:
step 1
we know that
The scale drawing is
The dimensions of the kitchen in the blueprint are
L=3(1/4)=3/4 in
W=5(1/4)=5/4 in
step 2
Find the actual dimensions of the kitchen
Divide the dimensions of the kitchen in the blueprint by the scale drawing
L=(3/4)/(1/16)=12 ft
W=(5/4)/(1/16)=20 ft
The area is equal to
A=(12)(20)=240 ft²
step 3
Find the cost of the tile for the kitchen
7(240)=$1,680
In swimming pool, the area would be only 5 pieces of rectangles since the top would be open. But if each area needs 1ft thick of concrete, then the length and width will be increased 2ft, but height only increased 1 ft. Make it length=20ft, width= 15ft, height= 10ft
Then to find the swimming pool area that need to be put some concrete the formula is:
Swimming pool area= length x width+ 2(length x height) + 2 (width x height)
Swimming pool area= 20ft x 15ft+ 2(20ft x 10ft) + 2( 15ft x 10ft)= 300ft
+ 600 + 300= 1200
Then to find the swimming pool area that need to be put some concrete the formula is:
Swimming pool area= length x width+ 2(length x height) + 2 (width x height)
Swimming pool area= 20ft x 15ft+ 2(20ft x 10ft) + 2( 15ft x 10ft)= 300ft
