A.
360 mm²

B.
390 mm²

C.
420 mm²

D.
450 mm²

Answer 1

plz help!

Answer 2

i think its a l*w*h

Answer 3

ummmm well i don't think it is........ actually IDK!

Answer 4

the area of the rectangle is 12 * 24
and the triangle area is 0.5 * base * height

Answer 5

ok?

Answer 6

he mean 12*24

Answer 7

the base of the triangle is 36-24

Answer 8

ok so then if we do 36-24 then it is 12

Answer 9

yea so you now can find the area of the rectangle and area triangle and add them together

Answer 10

then do we do 12 times 24 to get 288 then and add 12?

Answer 11

@welshfella

Answer 12

No 288 is the area of the rectangle That is correct
Now you need to find the area of the triangle
12 is the length of its base
and its height is also 12

so you find the area of triangle using

Area = 0.5 * base* height

Answer 13

ok

Answer 14

so do we do 12 times 12 divided by 2?

Answer 15

yes


then add the result to 288 to give you the final answer.

Answer 16

ok so the answer is 360 which is A?

Answer 17

correct

Answer 18

thxs both of you!

Answer 19

yw

Answer 20

A.
324 mm²

B.
243 mm²

C.
162 mm²

D.
81 mm²

Answer 22

@welshfella

Answer 23

you should be able to do this one using the same formula as the first one
The area of the square inside the triangle = 9 * 9'
and the area of the triangle
= (height * base) / 2

Then to get area of shaded part its

area triangle - area of the square

Answer 24

AS you can see from the diagram the length of the base of triangle = 18 and the height = 8 mm
