Question

The formula for the area of a triangle is . What is the length of the base, b, of a triangle with an area, A, of 110 m2 and a height, h, of 10 m? 22 m 2200 m 11 m 1100 m

Answer 1

Answer : The length of the base is, 22 m

Step-by-step explanation :

As we know that the formula of area of triangle is:

`A=(1)/(2)* b* h`

where,

A = area of triangle =
`110m^2`

b = base of triangle = ?

h = height of triangle = 10 m

Now put all the given values in the above formula, we get:

`110m^2=(1)/(2)* b* (10m)`

`b=22m`

Thus, the length of the base is, 22 m

Answer 2

A = (1/2)bh
b = 2A/h
b = 2(110 m²)/(10 m)
b = 22 m . . . . . . . . . . . . corresponds to the 1st selection
