Question

What is the area of the composite figure shown?



A. 600 cm2

B. 1,200 cm2

C. 1,287.5 cm2

D. 2,100 cm2

Answer 1

so the double lines on the edges show that all the sides are equal. this means the base in the trangle is also 40 cm, then you have the height which is 20 cm
therefore you take the equation 1/2 * base * height
1/2 * 40 * 20

Answer 2

LOST

Answer 3

alright
so the area of a triangle is \[\frac{ 1 }{ 2 } \times base \times height\]
looking at the picture we can see that the two lines on each of the sides, this means that the sides are equal lengths. so

Answer 4

600

Answer 5

this is where we get the \[\frac{ 1 }{ 2 }\times 40 (base)\times 20(height)=400\]
this is for the area that is missing. so this is the ammount we will subtract from the whole square

Answer 6

B. 1,200 cm2

Answer 7

does this make sense @adams07280728
we took the full area minus the missing area, after we found the missing area first

Answer 8

yes
