Area of Triangle= ( h*w ) /2.
So, 12 times 5 is 60. But then, you need to divide by 2 to get 30 sq. inches. Hope this helped!

Hello!

The formula for the area of a triangle is A=1/2bh. Let's plug this into the equation below.

A=1/2·5(12)
A=1/2·60
A=30

The answer is B. 30sq. in.

I hope this helps!

noname [10]

Answer:

a. 17.80 b. 71.20

Step-by-step explanation:

I used to hate percents. Let me teach you a trick:

take the og value (89) and multiply it by the percentage (20% or 0.2). Then once you have that answer (17.80), subtract it from the og value (89-17.80). That's your answer for how much you still owe! (71.20)

any other follow up questions? Just ask :)

1. BUILD A FENCE Mrs. Chen wants to build
Snezhnost [94]

Answer:

  180 ft

Step-by-step explanation:

The perimeter of a geometric figure is the sum of the lengths of its sides. Opposite sides of a rectangle are of equal length, so the perimeter can be figured as twice the sum of the length of adjacent sides:

  2(60 ft + 30 ft) = 180 ft

Mrs. Chen needs 180 feet of fence.
