Answer:
96
Explanation:
large rectangle area = 7* (4+3+5) =7*12 =84
top & bottom 2 little triangles:
look at the bottom one:
triangle area formula = 1/2 base * height
so it's a right angle triangle, so the height is 4, base is 3
so area = 1/2 * 3* 4 =6
you have another one on the top
so 12
total = 84+12 =96
