Question

PLSSS I NEED HELP URGENT!!

can someone please help me find the answer to this they want me to find the surface area of it

Answer 1

as below

Explanation:

add up the surface area of each side of this object

this object has 5 sides

2 of the sides are equal triangles so we could add those up to make one whole rectangle. and if we do that then there are only 4 sides

the two triangle sides add up to one rectangle side of 4 *3 = 12

the bottom side facing downwards = 3 * 7 = 21

the back side facing away = 4 * 7 = 28

the front side at an angle = 7 * 5 = 35

12 + 21 + 28 + 35 = 96
`cm^(2)`

Answer 2

Explanation:

You have three rectangular faces and two triangular faces. Each rectangular face has an area equal to xy. Each triangular face has an area equal to xy/2. So the total area will be

A=5(7)+3(7)+4(7)+4(3)/2+4(3)/2

A=35+21+28+6+6

A=96cm^2
