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?

OpenStudy (anonymous):

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

OpenStudy (radar):

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

OpenStudy (anonymous):

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