Find the area of the rectangle
find the area of the triangle
Add the two areas.
you have answer.
OpenStudy (anonymous):
huh
OpenStudy (radar):
Hint: area of rectangle is A= 2 ft X 30 ft = 60 sq. ft.
OpenStudy (radar):
Do you know the formula to calculate the area of the triangle?

no
OpenStudy (radar):
Here are the key items of info: Base = 30 ft, Height = 20 ft. In order to save you time taking to look it up on google, or in your work book the formula is
area A=.5Bh
where B=base and h = height. Now go at it.
OpenStudy (anonymous):
so is it 36000
OpenStudy (asadkarim7):
area of tri.. !/2 b h
1/2 x 30 x 20
= 3000
area of rec
30 x 2 = 60
3000 + 60
3060
OpenStudy (anonymous):
3060 is the final answer?? it says its incorrect

It seems to be larger, I will double check
OpenStudy (asadkarim7):
sorry its not 3000 its 300
OpenStudy (anonymous):
Asad is wrong...!!!!
Area of rectangle = l x b = 30ft x 2 ft = 60 sqft
1 1 600 sqft
area of trianlge = ---- x base x height = --- x 20ft x 30 ft = ---------- = 300 sqft
2 2 2
OpenStudy (radar):
thats more like like it, so the final answer would be 300+60=360 sq ft.
OpenStudy (asadkarim7):
yeah 360 ft^2

so total area of the figure = area of rectangle + area of triangle
= 60 sqft + 300 sqft = 360 sqft
