for number one, the answer is 225in^2
so you find the area of each and add it all together.
rectangular base: 5*7.5=37.5
Rectangular side: 5*10=50
Rectangular side: 5*12.5=62.5
Triangular side: 7.5*10*1/2=37.5
Triangular side: 7.5*10*1/2=37.5
add them all together:
225 in^2
And question 2:
Rectangular sides: 18*4.7=84.6
Rectangular sides: 18*4.7=84.6
Rectangular base: 18*5=90
Triangular sides: 5*4*1/2=10
Triangular sides: 5*4*1/2=10
Then add it all up!
84.6+84.6+90+10+10+90=279.2
279.2 in^2
