Question

Please help me get the correct answer

Answer 1

56ft. Because 7 times 8 is 56.

Answer 2

The area of triangle is 28 ft².

Step-by-step Step-by-step explanation:

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

`\star{\underline{\boxed{\sf{Area_((\triangle))= (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))= (1)/(2)bh}}}`

`{\implies{\sf{Area_((\triangle))= (1)/(2) * b * h}}}`

`{\implies{\sf{Area_((\triangle))= (1)/(2) * 7 * 8}}}`

`{\implies{\sf{Area_((\triangle))= \frac{1}{\cancel{2}} * 7 * \cancel{8}}}}`

`{\implies{\sf{Area_((\triangle))= 1 * 7 * 4}}}`

`{\implies{\sf{Area_((\triangle))=7 * 4}}}`

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

Hence, the area of triangle is 28 ft².
