Use Heron's formula to find the area of the triangle. Round to the nearest square foot.

Sphinxa [80]

Answer:

A ≈ 2 ft²

Step-by-step explanation:

The area (A) of a triangle using Heron's formula is

A = $\sqrt{s(s-a)(s-b)(s-c)}$

where s is the semiperimeter and a, b , c the sides of the triangle.

s = $\frac{a+b+c}{2}$ = $\frac{4+4+1}{2}$ = $\frac{9}{2}$ = 4.5

Then

A = $\sqrt{4.5(4.5-4)(4.5-4)(4.5-1)}$

= $\sqrt{4.5(0.5)(0.5)(3.5)}$

= $\sqrt{3.9375}$

≈ 1.9843...

= 2 ft² ( to the nearest square foot )

1/8 of pizza cost 2 dollars. In an hour, 6 1/4 pizzas were sold. How much money was made at the food booth in that hour

Darina [25.2K]

First of all, you would make 6 1/4 into an improper fraction. This makes it 25/4, then you multiply it by 2 to get 50/8 and have common denominators. Divide that by 1/8, which would be 50. Then since each 1/8 costs 2 dollars you would multiply 50 by 2. So, the answer would be that they made 100 dollars.
