Question

What is the area of the triangle ?

A) 64
B) 56
C) 48
D) 112

Answer 1

`\text{B) }56\:\mathrm{cm^2}`

Explanation:

The area of a triangle with height
`h` and base
`b` is given by
`A=(1)/(2)bh`. By definition, the base and the height must intersect at a 90 degree angle. Therefore, the diagram gives a base of 14 cm and a height of 8 cm. Substituting these values, we get:

`A=(1)/(2)\cdot 8\cdot 14=\boxed{\text{B) }56\:\mathrm{cm^2}}`
