Thank you We sneak in and here's your smoke too

00:05

Sure Brought to you by square units You'll be able

00:08

to afford a one bedroom apartment someday Well all right

00:14

Triangle shown below Right here as an area of two

00:18

hundred ten square units How long is the base of

00:22

the triangle face this time and here's A potential answers

00:28

You're feeling all numbers All right Well so to figure

00:32

this one out we're gonna have to know a formula

00:35

That's Great but uh not just any form This point

00:40

Area of a triangle you one half based on time

00:43

Okay so now what do we do with this information

00:46

Well we have a couple of numbers we can plug

00:48

into this formula of ours We're told that the total

00:50

area is two hundred ten square units so we can

00:53

replace the words area of a triangle with two Ten

00:57

and we can tell they looking at the diagram that

00:59

the highest fifteen So now our formula is to ten

01:03

equals one half base times fifteen And if we divide

01:08

to ten by fifteen we get fourteen with magic calculator

01:12

there Andi out Fourteen equals one half of face Well

01:16

Multiply both sides by two To get rid of that

01:18

half their way Get twenty eight equals b or base

01:23

So there we go The answer's aye aye is an 00:01:26.617 --> [endTime] ample living space
