Respuesta :

56ft. Because 7 times 8 is 56.

Answer:

The area of triangle is 28 ft².

Step-by-step explanation:

Here's the required formula to find the area of triangle :

[tex]\star{\underline{\boxed{\sf{Area_{(\triangle)}= \dfrac{1}{2}bh}}}}[/tex]

  • [tex]\purple\star[/tex] △ = Triangle
  • [tex]\purple\star[/tex] b = base area
  • [tex]\purple\star[/tex] h = height

Substituting all the given values in the formula to find the area of triangle :

[tex]{\implies{\sf{Area_{(\triangle)}= \dfrac{1}{2}bh}}}[/tex]

[tex]{\implies{\sf{Area_{(\triangle)}= \dfrac{1}{2} \times b \times h}}}[/tex]

[tex]{\implies{\sf{Area_{(\triangle)}= \dfrac{1}{2} \times 7 \times 8}}}[/tex]

[tex]{\implies{\sf{Area_{(\triangle)}= \dfrac{1}{\cancel{2}} \times 7 \times \cancel{8}}}}[/tex]

[tex]{\implies{\sf{Area_{(\triangle)}= 1 \times 7 \times 4}}}[/tex]

[tex]{\implies{\sf{Area_{(\triangle)}=7 \times 4}}}[/tex]

[tex]{\implies{\sf{\underline{\underline{Area_{(\triangle)}=28 \: {ft}^{2}}}}}}[/tex]

Hence, the area of triangle is 28 ft².
