Question

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?

Answer 1

Answer:75 square inch

Explanation:

easy

Answer 2

first, we'll need the area of a single triangle
then we'll multiply that by 3 to get our answer

to find the are of a triangle, we multiply height times base then divide that by 2
so.. 5 x 10 = 50; 50/2 = 25
if 25 = one triangle
then 25 x 3 = 75 = three triangles

answer - 75 sq. in.
