Question

In a right triangular ground, the sides are adjacent to right angle are 50m and 80m. Find the cost of cementing gorund at rs. 5/sq.m​

Answer 1

H²=s1² +s2²

50²=30²+x²

2500-900=x²

1600=x²

40²=x²

x=40

Area of triangle =½*base *height

=½*30*40

=30*20

=600 m²

Answer 2

Answer:

Rs. 10000

Step-by-step explanation:

Area is 1/2 base x height

Area is equal to 1/2 x 50 x 80

Area is equal to 2000 m2

Cost of Cementing is equal to 2000 x 5

Cost of Cementing is equal to Rs. 10, 000
