For a project, you need to make three triangles out of cardboard. each triangle has a height of 5 inches and a base of 10 inches. which equation can you use to solve for the total amount of cardboard you will need?

Option 1st is correct

Step-by-step explanation:

Area of the triangle is given by:

where,

A is the area of the triangle

b is the base and

h is the height of the triangle.

As per the statement:

For a project, you need to make three triangles out of cardboard.

Each triangle has a height of 5 inches and a base of 10 inches

⇒b = 10 inches and h = 5 inches

Since,  you need to make three triangles out of cardboard

⇒

Therefore, an equation can you use to solve for the total amount of cardboard you will need is,

11

step-by-step explanation:

32.50-7.50=25

225/25=11

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
