Question

A house of size 25m 25m is constructed in the middle of a plot 30 m x 35 m. A garden undeveloped aroun
the house. Find the total cost of developing a garden around the house at the rate of 360 per m².​

Answer 1

Answer:

please mark me as brainliest please and follow me....

Step-by-step explanation:

Find the perimeter of triangle

i. e.

S+S+S

40+20+40=100

total cost =Rate per metre *Perimeter

=100*15

=Rs. 1500

Answer 2

Answer:

Side of square plot =24m

Length of house (l)=18m

and breadth (b)=12m

Now,Area of square plot =(24)²

m²

=(24×24)m²

=576m²

Area of house =18×12=216m²

∴ Remaining area of the garden =576m²

−216m²

=360m²

Given, cost of developing the garden =Rs.50 per m²

Therefore, the total cost =Rs.50×360=Rs18000
