Answer 1

A

Explanation:

For a right triangle

`A=(ab)/(2) \\((10.4)(15.3))/(2) =79.56`

This is the same as the other triangle because they are the same size because of congruency

Area of the rectangle

`a^2+b^2=c^2\\`

`√((10.4^2+15.3^2) =c`

`c= 18.5`

18.5 x 7 = 129.5

Add them all up

129.5+79.56+79.56= 288.62
