A triangle has a height of x meters and a base of 14 meters. Write and solve an inequality for the values of x that give an area of at most 112m²

Answer 1

What is the formula for a triangle?

Answer 2

Area = ½ × b × h

Answer 3

we know that the area is 112 and the base is 14 right?

Answer 4

yes

Answer 5

so lets plug them in:
112 = .5 x 14 x h

Answer 6

so lets alter the formula to solve for H or the height:
h = .5x14/112

Answer 7

got it thanks!

Answer 8

I got 16 lets plug it in and see if it is right
.5 x 14 x 16 = 112
