plese answer fast

b) Find the area of the remaining portion of the field.

c) Find the cost of levelling the remaining field at the rate of ₹5 per sq m.

(a)

(b)

(c)

Step-by-step explanation:

Solving (a): The area of the flower bed

Given

The area is:

Solving (b): The area of the remaining portion

Given

First, we calculate the field area

Subtract the area of the flower pot from the filed area to get the area of the remaining portion

Solving (c): The cost of leveling the remaining field

Given

Rate = 5 per square meter

In (b) above, the area is 821m^2

So, the cost will be:

for b its (t) and c its (d)

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
