Question

Find the area of the triangle. [? ] ft2 Don't round

Answer 1

Step-by-step explanation:

$Area = \: \frac{bh}{2} \\ : b = 16.9 \: h = 10.4$

$Area = \frac{16.9 \times 10.4}{2} = \frac{175.76}{2} = 87.88 {ft}^{2}$

Base = 16.9

height = 10.4

Area = ½b×h

A = ½(16.9×10.4)

A = ½(175.76)

Area = 175.76/2

A = 87.88ft²

Answer 2

Answer:

$\Large \boxed{\mathrm{87.88 \ ft^2 }}$

Step-by-step explanation:

$\displaystyle area \ of \ triangle \ = \ \frac{base \times height }{2}$

$\displaystyle area \ of \ triangle \ = \ \frac{16.9 \times 10.4 }{2}$

$\displaystyle area \ of \ triangle \ = \ \frac{175.76}{2}$

$\displaystyle area \ of \ triangle \ = \ 87.88$
