Your company will replace the asphalt roofs on all the buildings at the factory complex shown below. the buildings have flat roofs. you charge according to the total roof area. what is this area, in square yards? two roofs. the first consists of two rectangles and two triangles. the rectangles measure 20 yards by 30 yards. the triangles measure 5 yards by 20 yards. the second roof is a rectangle measuring 25 yards by 60 yards.

Total area  2800 sq.yards

Step-by-step explanation:

First roof  

2 rectangles       and      2    trangles

for rectangles area = b*h

then area of one rectangle = 20*30  = 600 sq.yards

We have 2 rectangles then  2 * 600 = 1200 s. yards

for triangles area 1/2 b*h

Then area of one triangle   = 0.5* 5*20  = 50 sq.yards

We have 2 triangles  then 2 * 50  = 100 sq.yards : 1300 sq.yards

Total area first roof  = 1300 sq.yards

Second roof    

Area of rectangle = b*h       = 25*60   =  1500sq.yards

Total area second roof  = 1500 sq.yards
