Question

Please help me get the correct answer

Answer 1

56ft. Because 7 times 8 is 56.

Answer 2

Answer:

The area of triangle is 28 ft².

Step-by-step explanation:

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

$\star{\underline{\boxed{\sf{Area_{(\triangle)}= \dfrac{1}{2}bh}}}}$

• $\purple\star$ △ = Triangle
• $\purple\star$ b = base area
• $\purple\star$ h = height

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

${\implies{\sf{Area_{(\triangle)}= \dfrac{1}{2}bh}}}$

${\implies{\sf{Area_{(\triangle)}= \dfrac{1}{2} \times b \times h}}}$

${\implies{\sf{Area_{(\triangle)}= \dfrac{1}{2} \times 7 \times 8}}}$

${\implies{\sf{Area_{(\triangle)}= \dfrac{1}{\cancel{2}} \times 7 \times \cancel{8}}}}$

${\implies{\sf{Area_{(\triangle)}= 1 \times 7 \times 4}}}$

${\implies{\sf{Area_{(\triangle)}=7 \times 4}}}$

${\implies{\sf{\underline{\underline{Area_{(\triangle)}=28 \: {ft}^{2}}}}}}$

Hence, the area of triangle is 28 ft².
