A field is in the shape of a right angled triangle whose base is 25 m and height 20 m. Find the cost of levelling the field at the rate of Rs 45/- per m $^{2}$ ?

Open in App

Solution

b = 25 m, h = 20 m

Area of the triangle $= \frac{1}{2} \times b \times h$ sq.units

$= \frac{1}{2} \times 25 \times 20 m^{2}$

$= 250 m^{2}$

Cost of levelling $1 m^{2} =$ Rs. 45

Cost of levelling $250 m^{2}$ = Rs. 45 $\times$ 250

= Rs. 11250
