Question

Art wants to cover an isosceles triangle with a height of 9 centimeters and a base of 7 centimeters in fabric. How much fabric does he need?

Answer 1

Answer:

31.5 cm²

Step-by-step explanation:

Calculate area of a triangle with this formula:

Area = $\frac{1}{2}$ base * height

Substitute in known values

Area = $\frac{1}{2}$ 7 * 9

Multiply 7 by 1/2

Area = 3.5 * 9

Multiply

Area = 31.5 cm²

Hope this helps :)
