The height of a triangle is 7 ft more than its base. if the area of the triangle is 30 ft^ what is the lentgh of the base
Dmitriy789 [7]
Since the area of a triangle is in the form
area=0.5(base)(height)
height=base+7
let base=x
area=0.5(x)(7+x)
30=3.5x+0.5x^2
multiply the equation by 2
60=7x+x^2
subtract 60 from both sides
x^2+7x-60=0
(x-5)(x+12)=0
thus  x=5 or x=-12 since we are only considering positive answers
x=-12 is rejected
so base=5 and height=5+7=12

zalisa [80]

The perimeter is just the sum of all of the outside edges

So, the perimeter is (2*14)+(2*7), or 28+14, or 42

So the perimeter of figure 1, with all of the information that you have given me, is 42 units
