Find the area of a triangle with a base of 7.5 m and a height of 4*

oksian1 [2.3K]

Answer:

15 units²

Step-by-step explanation:

Hi there!

$A=\displaystyle\frac{1}{2} bh$ where b is the base and h is the height

Plug in the base (7.5) and height (4):

$A=\displaystyle\frac{1}{2} (7.5)(4)\\\\A=\displaystyle\frac{1}{2} (30)\\\\A=15$

Therefore, the area of the triangle is 15 units².

I hope this helps!

Henry wants to buy a new table saw for his carpentry shop. He has saved $360 which is 2/3 of the price of the saw. How much does

Tema [17]

If 360 is 2/3 of the full price on a saw then your equation should look like this:

$360=\frac{2}{3} *x$

x is your unknown full price of the saw. Just solve for x now.

$360=\frac{2}{3} *x\\ \\ x=\frac{3}{2} *360=540$

This means that the full price is $540.

Hope this helps!
