for number one, the answer is 225in^2
so you find the area of each and add it all together.
rectangular base: 57.5=37.5
Rectangular side: 510=50
Rectangular side: 512.5=62.5
Triangular side: 7.5101/2=37.5
Triangular side: 7.5101/2=37.5
add them all together:
225 in^2
And question 2:
Rectangular sides: 184.7=84.6
Rectangular sides: 184.7=84.6
Rectangular base: 185=90
Triangular sides: 541/2=10
Triangular sides: 541/2=10
Then add it all up!
84.6+84.6+90+10+10+90=279.2
279.2 in^2
