Find the area of the triangle. a. 620 sq. m c. 100 sq. m b. 200 sq. m d. 180 sq. m

100 sq. m

Step-by-step explanation:

So, first, we need to know the formula for the area of a triangle.

A=BH/2

In this case, we know the base and the height (B and H respectively), and we just fill it out.

A=10*20/2

A=200/2

A=100.

Lastly, don't forget the units, so, A=100 sq. m

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
