Question

Sue bought a triangular shaped piece of wood with a height is 12.4 inches and a base of 4

inches She plans to cover the front with a piece of fabric, how much fabric will she

need?

Answer 1

24.8
`inches^(2)`

Explanation:

Height of a triangular shaped piece of wood bought by Sue =12.4 inches

Height of a triangular shaped piece of wood= 4 inches

Area of fabric required to cover the triangle = Are of a triangle

As we know the area of triangle=
`(1)/(2)` × base ×height

So, Area of a triangle=
`(1)/(2)` × 12.4 ×4

So, Area of a triangle= 12.4×2

Area of a triangle= 24.8
`inches^(2)`

Amount of fabric required to cover area of a triangle is 24.8
`inches^(2)`

Hence the correct answer is 24.8
`inches^(2)`
