Question

please answer the thirteenth sum​

Answer 1

Answer:

Length of grassy plot=125m

Breath of grassy plot=74m

Width of path=2.5m

Step-by-step explanation:

Now, Let us Consider a Diagram for easy explaination.

First of all we need to find the area of the bigger rectangle.

So,

Length of bigger rectangle(L)=125+2.5= 127.5m

Breadth of bigger rectangle(B)=74+2.5=76.5m

Therefore, Area of rectangle,

=L ×B

$127.5 \times 76.5 \\ = 9753.75$

Again,

Area of Grassy Plot,

$= l \times b \\ = 125 \times 74 \\ = 9250$

Therefore, Area of Path,

= Area of Bigger rectangle - Area of grassy plot

$= 9753.75 - 9250 \\ = 503.75$

Therefore, Cost of leveling,

$= 6.80 \times 503.75 \\ = rs \: 3425.5$
