i need help
I assume that all the angles marked with squares are right angles so you have 2 rectangles: |dw:1443809856474:dw| can you see how I got that?
what is 27+27+72?
yes the squares are right angles so do i multiply all the "rectangles" and then add them
The area of a rectangle - I'm sure you know how to get that so subtract the small rectangle from the large one to get the answer (BTW @Future_Einstein - I think you are confusing the perimeter with th area)
dont listen to that there is an easier way
if the answer isn't 126 then ill delete my profile.
so do i add or subract?
So find the area of the 2 rectangles and subtract the smaller from the larger OR you go with @Future_Einstein |dw:1443810144627:dw| find £ rectangles and add them
well idk which one of you is right.......
we are both right - the answer will be th esame whichever way you do it
we both are technically but i find my aproach a lot easier. it is ultimately up to you.
ooooh ya i get how you explain it mathstudent55 and also how you do it future einstein
One way is to find the area of the large rectangle, 12 m by 15 m, and subtract the area of the small, cross-hatched rectangle, 6 m by 9 m.
it is not 'technically' - we are both right -period. In my case you find 2 areas, in yours you find 3 - but I agree that either way is perfectly valid.
Another way is to break up the figure into 3 rectangle shown below: |dw:1443810228909:dw|
