The area of a triangle is given by the formula a=1/2bh. solve this equation for the height, h, in terms of the base, b, and area, a.

The equation for the height, h, in terms of the base, b, and area, A is

Solution:

Given that area of a triangle is given by the formula:

Where,

A is the area of triangle

b is the base of triangle

h is the height of triangle

We have to find the equation for height in terms of base and area

So we have to arrange the equation in such a way that height can be found by using area and base

Given formula is:

Keep "h" alone in L.H.S and move the other terms to other side of formula

Thus height is expressed in terms of base and area

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
