Question

PLS HELP, AM NEEDING TO TURN THIS IN, IN LIKE AN HOUR​

Answer 1

48.25

Explanation:

When finding an area of a triangle it is area = base times height divided by 2.

AKA a =bh1/2

We can do that for all sides in this equation.

For the bottom we can do:

5*4.3=21.5 21.5/2 = 10.75

For one side we can do:

5*5 = 25 25/2 = 12.5

12.5 = one side, but there are three so,

12.5*3 = 37.5

37.5 + 10.75 = 48.25
