Answer:
Price of paint = Rs 16,640
Step-by-step explanation:
As 3 dimensions are given so the third one must be for ceiling.
So in this case, we can find area as follows:
Area = 2(length * width) + 2(length * height)+ 2(height * width)........eq1
Lets say:
Length = 8m
Width = 6m
Height = 4m
So putting value in eq1 we get:
Area = 2(8*6) + 2(8*4) + 2(4*6)
Area = 2(48) + 2(32)+ 2(24)
Area =96 + 64 + 48
Area = 208 sq. m
Now for calculating price:
Price of paint = 208 * 80
Price of paint = Rs 16,640

Answer:
JL = 21
Step-by-step explanation:
Given that K is on line segment JL, therefore:
KL + JK = JL (according to segment addition postulate)
KL = 2x - 2
JK = 5x + 2
JL = 4x + 9
Thus:

Solve for x



Subtract 4x from both sides


Divide both sides by 3


Find the numerical length of JL

Plug in the value of x

Answer:
264 cm^2.
Step-by-step explanation:
The area = 1/2 * height * sum of the parallel sides
= 1/2 * 12 * (28 + 16)
= 6 * 44
= 264 cm^2.
