Question

Which expressions can be used to compute the approximate area of triangle XYZ? Check all that apply.

Answer 1

Given:

In the given ΔXYZ,

Base = 22

Height = 23.1

Also,

Base = 31.9

Height = 15.9

To find the area of the given ΔXYZ.

Formula

The area of a triangle is

$A = \frac{1}{2} bh$

where, b be the base and

h be the height.

Now,

Taking, b = 22 and h = 23.1 we get,

$A = \frac{1}{2} (22)(23.1)$ sq unit

Again,

Taking,

b = 31.9 and h = 15.9 we get,

$A = \frac{1}{2} (31.9)(15.9)$ sq unit

Therefore,

We can find the approximate area of the triangle by following two expression

a) $\frac{1}{2} (22)(23.1)$ and

b) $\frac{1}{2} (31.9)(15.9)$
