Question

A rectangular grassy lawn measuring 50m by 30m is to be surrounded
externally by a path, which is 3.5m wide. Find the cost of the leveling the path at
the rate of Rs 5 per sq. m

Answer 1

Answer:

Find the cost of the levelling the path of the rate of RS 5 Breadth of the lawn including the path = 30m + 3.5m + 3.5m The cost of lavelling the path at Rs 5 per .sq.m.

Answer:Rs.3045

Answer 2

Answer:

rs 2800 is the total cost

Step-by-step explanation:

the rectangular lawn will be leveled through its border so we will be measuring the perimeter of the rectangle

i.e. 2(l+b)

l= lenght ;b=breath

l = 50 m

b = 30 m

2(50+30) = 2(80)= 160 m

then it's is given that its wide = 3.5 m

so we will be calculating the area upto which it will be leveled

so 160 x 3.5 = 560 m per sq.

if u didn't understand this , just calculate it in other way like this rectangle has its wides 3.5 m all over 4 sides of it so calculate all the sides area differently and then add then

175+175 =350

105+105= 210

350+210= 560 m per sq.

than its is given that the cost of leveling is 5 rs per m sq

so just multiple with area of the perimeter of the rectangle

i.e., 560 x 5 = 2800 rs .
