Question

find the cost of diggging a triangular piece of land whose base is 24 m and altitude 14m the cost of digging is 250 .50 per sq m

Answer 1

Find the area of the triangular piece of land:

Area = 1/2 x base x height

Area = 1/2 x 24 x 14 = 168 m²

Find the cost of digging the plot:

1 m² = Rs 250.50

168 m² = 250.5 x 168 = Rs 42,084

Answer: The cost is  Rs 42,084

Answer 2

Ok.
first we will find area
$\frac{1}{2} \times b \times h$
so taking half as 0.5 we get area as
0.5×24×14,
which comes to be
168 m2
now cost of one sq m=250.50
so cost of 168 sq m
168×250.50
42084 Rs
hope it helps you
